I like it too. I've decided to invest the time in a new pic, one where I can plan out some of the colors better. This was just a quick recolor to test a suggestion. Know any good fire painting tutorials?
Hahaha true. I find a smaller (proportionally) head tends to make the mech look more imposing, though I maaaay have gone a bit far. As for the 'hair', where is your sense of style? Of adventure? It's a giant robot! I figured you would have suspended disbelief well before hair became an issue.
And in this case, the 'hair' is just the exhaust from the 'engine' that runs this thing.
Oh, I agree to a point (and that link, btw, is crazy cool); but I guess it all falls on the spectrum of what you consider cool. Your aesthetic is very utilitarian, mine tends to be a little more ornate (for instance, while I think utility is important, I have no problem erring on the side of style vs utility). And pose is important! It helps convey the attitude of your piece, the personality of your machine! Compare the differences to Kunio Okuwara's Dragonar Unit 1 vs the same machine drawn by Masami Obari. It's leagues apart in terms of presentation.
