Ok so I've added a number of bigger contributors to the credits page of smogon:

The site update system is going through a change in the content management system so I'm not going to update it for a while, but I will soon enough. I only put some contributors just to familiarize myself with editing html on the new system.
In terms of Talonflame I'll update it for sure, but if a sprite has already been animated and such I feel the onus is more on the QC person to assist with editing the animation rather than the original animator. You did only edit the body so ideally yes it shouldn't be too hard. We have posted a number of applications in here that can assist with gif editing.
I'll probably be editing one sprite that has an animation, and I too will edit up the animation to reflect this minor change. But ideally again once a sprite is in animation it is good enough to not have to give huge edits.
As a side note those who know me well are aware I'm a theatre creator so while a performance can always be better there is opening night ahead. Our first opening night event was before the massive leaks where we made sure most of our stuff was stable. Our next big deadline for me was at the point where PS could begin beta. Once the ladder for gen6 officially starts I'd love for us to have great fronts and backs. Then maybe I can but the PS guys on adding in our animations.
My priority right now is entirely on functional fronts and backs, so outright replacing sprites that already are ready for animation such as Flabebe just doesn't seem productive to me. Just letting me know you think there is a problem with the sprite and I'll take it off animation ready status. I do think Flabebe is fine, Quany has noted the outline is bright so I'm waiting on that QC to occur. I of course have not seen a redone version, but would an edit suffice instead of building a new sprite entirely?
I also understand people just want to be part of their favorite new mons, and I think that is wonderful, but as I've said before I would like to eventually finish the project, and at the same time I do want everything to look great.
I'm also picking up Mega-Houndoom after putting that down a bit, he's a big bugger.
Also sandz is a genius, the sprite gen now has shiny animated sprites available:

There aren't many but we had enough to test it and have it ready for more!
A credit link to the thread is also on the generator.
