Starcraft Birthday Gift

Pff... I've been quite busy working on some comissions
here is a Birthday Gift for the Husband of one of my teachers~
Starcraft Themed!!! 
It's my very first time E-V-E-R drawing some mecha-robot-badass style thingie... ;U
I accept any constructive critiques 
I'm somehow new working with this kind or realistic style and brushes... I tried some experiments with light... :S

I really hope they like it!
