Obviously it's your 2nd colouring and there are going to be flaws (shading mainly), but you've got a confident approach, and original style (well, I say original in these days of high gloss realism). Reminds me a bit of AK46 in that respect - like a breath of fresh air, because not many people are doing your style. Love the choice of colours - bold, bright, little rough around the edges - I like that. Mangaka - aka Mr Moonlight, (you should check him out) also resists the 'neat and tidy' look and it works brilliantly for him.
Yeah, keep experimenting till you find the style you like best and keep practising and above all - keep submitting!! I'll be looking out for ya!
