Thurn the well groomed barbarian

You have been visited by a Critmas Fairy! We fairies are trying to show the world we can give critique to others without being downright criticising, as per the spirit of CRITmas (fav.me/daqfq97). Mind if I just hop on to business, then?

First things first: Great concept; love how you executed it too - I've never seen a character presented on a floating rock like that, ever! I also love the top light; never seem to get enough from that. Nice job!
I also noticed you rendered the different materials so nicely. the leather parts, especially! Very convincing.

I do seem to spot some anomalies in the guy's anatomy, or rather, his proportions. I'll go over the bits that I could spot easily:
Firstly, his one arm is way bulkier than his other. His one foot seems to be too short, and in his face I think his nose is a tad short, his mouth a bit narrow and even for a very tostesteron-laden character, that chin is rather big. As it is, his features seem to be a bit crammed too close together - I think some slight changes there will make a big difference already.

That's all I've got. I hope I'm not coming across as brash or overly stern - I really don't mean to!

I hope 2017 will see you make much much more character portraits like these, but let me start by wishing you a very nice evening.
Cheers,
BATTLEFAIRIES

(PS: Please don't mind the stars. I don't think the rating system is all that good so I'm just giving everyone 3.5's. Thank you for understanding)
