How's this for my models?

[Shadowth117]

...... Well, I asked for suggestions, so suggestions I got (even though it's always irritating to go back and correct mistakes).

Regardless, I went back and corrected the mistakes you pointed out, Lexou.

I shorted and fattened the arms, made the hands bigger, placed the tail in a different location, and made the eyes larger (I had no idea what you meant by "rigged" but I was assuming that you meant that the eyes were kind of small). To top it all off, I even managed to put the Koopa in a natural leaning position!

*Updated Koopa pics*

Anything else that needs changing?

The shell would probably look a little bit better with a good bump map, but if you're not up for making one its pretty good as it is.
