Mate...you are doing better than I.....
I will say (Im a noob so ignore me if Im wrong LOL) I think his skin now looks like wax or plastic...if you get my drift??
I think with the backlight you have lost too much detail on his front....its in too much of a shadow. Dont know if you can lighten it maybe a tad?
With the elbow I would pull the upper left out just a touch..to round it off a wee bit and slightly close off the channel running from the outer elbow down the forearm.
I wouldnt give him a full eye mate...it looks ok but maybe can you open it a little??? Give it a fat/black eye look...like a boxer.
Maybe add some texture to the skin...like smeared sandpaper or something? and what colour will it be?? Maybe a lightish grey with a blue/green hue..like a cadaver. I did prefer the B&W thing (sorry personal pref)...
Dont give up mate...I nearly did but Mayaniac saved my arse...so if I can keep going..so can you.
