The character design is pretty good, but the drawing itself isn't so great. Every part of him looks kinda round, almost gooey, like clay. It's like he has no bones... look at how round his leg looks while bending... there is no knee @_@.
Also, kind of un-detailed, everything being too rounded... Also would benefit from some more shading. He looks kinda 2d because of the basic shading.
The stance and perspective are odd as well, not consistent through the entire drawing... btw my favorite part is his boot at the bottom, it just looks nice <_<
