Looks really good for the most part. The only areas that need improvement IMO would be the shoulder pads. They don't read very well. Looks like bad compression artifacts or something. Probably just too low pixel density, but It's blurry.
As for the concept, It's a nice looking character, but I think it misses the mark for a steam punk scientist. The only thing that reads as scientist would be his physique and the fact that he's wearing glasses. And the only steam punk hints would be the colour and intricate designs for the fabric on his vest. But there's no watches hanging from it

.
His glasses should be a gadget used in his sciencing of things... he should have one arm that is all robotic and stuff...
The gadgets look like toys too.
But like I said, i like it for the most part, I think it needs some improvements in the concept department. But the execution is great for the most part.
Good job guys
