Dude, those animations are on point! It looks acts exactly the way 06 Sonic does. He even does the little shoe-bang tap in his idle animation. Can't wait to see more!
Have you thought about doing the other characters from Sonic 06, such as Amy, Silver, Shadow, Blaze, Rouge, and Omega? You'd be the first person to do an Omega MD2 if you did.
Anyways, yeah good stuff man, with you being able to use fragmotion to use proper game animations and convert them to frames, the possibilities are endless as to what you could make.
I think we can safely say that you have the superior Sonic 06 md2.
Mine looks like garbage compared to yours.
Definitely keep doing it by doing several models at once before updating the pack. I'd love to receive the content as it is finished, but I would rather update my folder less often. Besides, having more content makes every release that much better! So don't be afraid of completing more models before you update the pack. :)
