Dude, You need to take the polycount down a bit. almost 3k polys, and it has no
modeled in folds, creases or nothin. You need to do some serious poly zappin.
I'm not exactly lovin this model, but what it needs is some tough love man. Kill
them polys O_O. Looks like the legs are about 10 or 12 sided. Which was one of
your main problems. If your doin a low poly model, then should almost always start
out with a 8 or 6 sided clynder for the legs, trust me, it will save alot of polys.
And also if you want to save polys, I suggest doing the big toe big block thing.
I used to hate doin it, but it looks good after you give it a good skin and saves alot
of polys. Needs alot of work, but its a start.
