First of all: I love the concept, so don't get me wrong - I'm not trolling, I'm critique'-ing. Proportion could use some serious work. Lighting is confusing... it would be better IMHO if the welding sparks were the primary/only light source. The foreshortening on her left leg is a little exaggerated. The welding sparks and the steam coming out of the mechanic's back are understated. If you want a short, short review - the subject matter is great. The design concept is great. The delivery... well... looking at what you have, I know you can shade great - but you don't pay attention to light sources. I know you can draw well - but you're slacking on proportion. Looking at your other artwork, I'll say that you've given this about 50% of your capability - ergo I'll give you 50% of 5 stars for your efforts. Once again - I'm not trolling. I'm simply comparing this to your other work and making a judgement call.
