Mata: I distinctly recall you saying after making 'First Date' that you were through with 3D. Yet, you used it again. Now you say that you will return to 2D. I am skeptical that you will, but here is something to think on:
Please do not completely. I understand the length, and I sympathize, but it does not all have to be like the first few... surely you could at least have Sarah walk in a direction other than directly across the screen or something... and the 3D is quite stunning visually. Most people I have tried to convert have liked the 3D and found the others "primitive", "amateur", "basic", and/or "not so engaging and complex as Magical Trevor [a catchy weebls-stuff toon]".
So, I propose a blend. Keep it when it has high visual yield (a la the trans-city jump in 'First Date'), scrimp where it does not, and above all keep it smooth and consistent.
Of course, you are the Mata. I will not presume to order you, and these should be taken as well-meant strong suggestions.

Also, is it just me, or is Sarah getting shorter while her wings enlarge?

I will be using 3D occasionally, but usally as special effects. The First Date episode was completely in 3D and it just took way too long to make, although the end result did look nice.

Considering that the first Little Goth Girl episode was made after I'd only been using Flash for about a year I think that it is very fair to describe the animation as amateur or basic. Bear in mind that Magical Trevor was made after at least four year's experience, possibly more like five or six. You wouldn't expect people to pick up a pencil and suddenly be a master, so why would people expect the same from an animator?

All of which I tell people who say these to me. Most teens, oddly, value the incredible innovation of a Flash series with a plot over the early graphical [insert something politically correct here], while most adults think that basic animation means simple laziness. I would expect the other way around, but then I expect a great deal of sanity from humanity and often am disappointed...

While I think you might be overstating things to describe a plot as an incredible innovation, your support is kindly received!

Yes, that is odd. I've always been slightly surprised by the way that the early LGG episodes continue to be so popular in terms of hits considering their lack of technical finesse. Maybe once I've finished my PhD I'll go back and polish them up... But don't worry, I'll leave the originals online too!

Touching them up might be fun, but the original quick wing morph is classic. I'd love to see a bit more detail on the early counselor. I like the old ones overall, and some of them are funnier because of the primitive style. the goth bunnies aren't incredibly detailed, but they still make me laugh every time I see that animation.
"That wasn't there a moment ago..."

No, I am very careful of my speech; overstatements are rare from me.
I have been to many major Flash sites, and while I have seen consistent series (sharing characters, a theme, etc.), and have seen great plots, I have never seen a long series with an engaging and overarching storyline. One would expect someone to have done it sooner, but apparently Flash is culturally too much of a hobbyist thing (think short loops and animutation) for that sort of masterwork to go into it.
If you have found another example of this, though, by all means tell me! In this I would love to be wrong...

I have to agree with Jatopian that, whilst many flash shows/animations/cartoons (delete as aplicable) have good graphics, there are remarkable few that are developed into full series. If you take a spin round somewhere like AlbinoBlackSheep or NewGrounds there are many one-offs. Yet you seem to far prefer storylines and continuity. The only other example of this that springs to mind is Weebl and bob, although this doesnt display the same desire for technicallity that your animations do.

Anyway, enough complimenting you. Now hurry up and finish your PhD so there can be more Mr Snaffelburger!!

Funnily enough, I'm taking a break for a couple of days from my thesis to work on a new Mr Snaffleburger. Goodness knows how I'm going to find the time to make my halloween animation though.

Personally I really like the Weebl series. I might not always find it particularly funny (but many people would say exactly the same thing about my animations, so that's just a personal taste issue, and no reflection on the writing) but Jonti does experiment with new visual ideas and Flash tricks more than many animators, so I have a lot of respect for him in that regard.

I saw 'weebles' and need to add spam:

After doing out weekly leg workout one day my legs were perticuarly jello-y feeling and I exclaimed to my dad who wanted me to do the last set "I'm not a weebl! I fall when I wobble!"
