I had gotten bored of doing constant human horse and cat anatomy and decided to edge my way into something a little less realistic. Actually, I think this will help me in something very specific, as I may want to throw in a few skeletal figures. ;D

First of all, hedgehog quills do NOT remain intact on the bones; I only added them for a silly effect. x3 So take no notice of them.

As for the unfinished picture of Bean's skeleton (I left the hand and foot out because I figured anyone who even so much as looks at it would get the picture) on the right, I designed him so that he can clearly be recognized as "half-evolved". Notice how he has both a beak AND molars. Also, I noticed something rather euphoric.

As the bird characters of Sonic the Hedgehog HAVE NO WINGS (normally), that should mean that they are reaching a new age of development. Most likely, their bone structure is becoming less hollow as time passes. So I made it look as if the little duck's bone structure is thickening "around the edges". The fore-arms, the feet, the legs especially. The only TRULY birdlike feature I kept for him was the delicate skull (courtesy of my seagull skull, which I used as reference with a little bit of warping.)

Since anthro skulls are so friggen HUGE, I had to make up a reason WHY they could hold them up on those tiny necks. And that is-- because the skull itself is light and delicate. Yes, this makes a blow to the head VERY dangerous. But that's the only answer I've got. ==;

I might be altering my ideals on their body-structures, but that may come later after I've learned more.
If you don't like it, tough luck.
