I think Quareni has summed it up pretty well. The pose is nice and striking, just right for what you are representing and the sculpting is a good start, but little lacking in refinement.
From your description it sounds like you are learning as you go with this guy though, so for an early attempt it\'s fine.
A problem that you will probably find is that the lack of sharpness and smoothness on the armour plating will definately not help the overall look once you paint it. In future try using a blade to cut the Green Stuff edges sharper, and perhaps mix the GS with a more solid sculpting material (like Milliput) and then file it into the shapes you want once it has dried.
I like some of the details like the dude on the leg and the chapter symbols. Did you make them off the model then stick them to him before they dried?
If not you should try that, because it\'s a good way to work on details. Lay some plastic (like a baggie) down on your work surface, wet it and roll a thin sheet of Green Stuff onto it. Add the details to the sheet using sculpting tools and a knife, then peel it off the plastic sheet and adhere it to the model before it dries.
The same sort of thing works for tabards and cloth, and will get it nice and smooth.
The chain could use a bit of work but don\'t stress about that, it\'s not easy to do. There was a link to a good tutorial put up a little while back. I\'ll try and find it for you.
EDIT - That was easier than I thought,
here\'s the tutorial.
