You can bend your leg like that. I'm doing it now. Well, not now but I did it a moment ago.

As for colours, I'm thinking my monitor is brighter/higher contrast than most people's because whilst I cant make out the 3 grass colours individually they certainly help make it less flat-looking.

Oh, and that's not AA under his shirt - it's shading under his belly. He's a golfer, after all.

I'd agree with the arm - more specifically the hand - but that's the best I could manage.I kept trying to bend it a little and it just looked ugly and elongated.
I used this image as reference but I was trying to literally just use it to refer to. I didn't want to try and make a pixel version of the photo, hehe http://www.1st-beginners-golf-swing-tips.com/assets/images/down-swing-1x250.jpg

The arm looks like it's brokeb :D

And the aa at the bottom of shirt makes this guy look round like he has a belly :D

His arms are just....strange and in an impossible position. Though I cannot exactly say if the front arm is bended, or if his hand is in a vary odd position, but it looks off. Also his left leg (Our view) looks like it's bending through, a leg cannot bend like that. Another comment is the amount of colours. There are alot of unneeded colours like on off the greens in the grass. I actually don't see it from a distance. This should be atleast brought back to 16 colours. But I still quite like the overall feel off the picture, though the pose is incorrect, it's still working.

Phew, all the comment I can spill out now.

Much better now, looks pretty good. Possibly darken the pixels underneath his right / our left eye to show a shadow of an eye socket.  ... up to you. Big improvement.

Yeah, I see what you mean about those eyes.

I'v given him slightly different shading on the face and removed his eyes - I've tried to just suggest a recess where his eye sockets are and accentuated them with some eyebrows. He looked okay without the eyebrows but with the it makes him look a bit older - more like a golfer, hehe.

I think those eyes really hurt it. They're too close together, I think they're too close to the hairline by far, and overall they just look weird. I think the only indication of eyes you should have is maybe a couple dark pixels near the bottom of his head. You could leave them off entirely, in my opinion.

Yeah, the grass tiling was obvious but I've never dabbled in tiling, so I've thrown together some new grass and given him some eyes... I can't fit much more face in!

Cheers guys

Dynamic. Looks great, but the grass is too tiled. The clothes are nice, but I'd like to see a little bit of face.

Heh, I like the idea of pixeling golf in action ^^
Maybe you coul rework the grass, tiling is a bit obvious.
