I don't see any problems off the bat, but if you want a more natural walk state, you might want to make the arms move back and forth. But it looks like you are off to a nice start.

What your doing right now is called pillow shading, most people do it when they are first starting out. Pillow shading is when you take a darker color and pretty much just go lighter as you get further inside.What you need to do is learn to use a light source, but don't worry, there are a few cool tutorials on the front page that can really help out some. I like this one to cover pillow shading.

But, I also made a edit of your base right now. Check it out, I changed a few lines, and made a step by step thing about how I shaded it.



Don't be mad if your first attempt doesn't look a lot like it, and things like that. I think I went a bit overboard myself. Hehe.

Good luck!

Haha, you actually didn't add a light source there either! If you look there is light coming off the legs on both sides(Meaning there is two suns comming from the NW and NE). I think light sources look alot better from just one diagnol angle(Like NW or NE) But you were probably thinking of using a light source from straight above, though this almost can look like pillow shading.

lol i forgot to post the updated one the one with the pillow shading is already been fixed ill post the new one later on today thanx to everyone for the tips

okay ive spoted one problem with your base's south movement state,
if you are walking you notice that your arms move in the opposite direction of your legs I.E; your left arm moves back while your left left leg moves forward. if you try walking the way your base is walking it would feel rather akward or like a robot.but its a common problem that ive seen in alot of bases.
