Nice work

Certainly an interesting thing to see The facial features are especially realistic however the anatomy stands in strong opposition to that, The blank background further ignites thought, and leaves a viewer in wonderment of what the artist’s purpose was behind this, It also highlights the presence of the man causing the same reaction nevertheless.

~~THINGS TO IMPROVE ON~~
Would have loved some backround detail just to accent the main piece a little more

I don't know how far you got with Osuka's contest. I also don't really even know who won it. There are so many things going on here, it's hard to keep track. I love how this turns out. Granted, I don't really know how it would work in real life. It's great to see a 3D drawing like this.

He really does look pretty grumpy. It's either that or bored. It's always nice to make something that's interactive for the rest of us. He really looks a lot like a kind of stuffed doll. The bulges make him look cute.

It doesn't look very good but you have still some skills. But sackboy is just too old figure.

What the guy below said

I just realized I commented on the texture already but oh well :x

But yeah, what the guy below said, specifically at the face. I think a bit more subtle effect would do.
Also, it could use a higher resolution as it's a bit blurry some places
Oh and he has a bit large facial features judging by the size of his head :P
