One side of me thinks it kind of looks cool, with the contrasting colors and stuff, but the other side thinks it's a bit too harsh and/or a bit sloppy. 8.3/10 overall.
6/10 Feels plain and flare stands out too much in my opinion. Also try not using static renders, renders that use action tend to be more easy to work with ^^
I know, if you go on my deviantArt: http://measky.deviantart.com then you'll notice that the work that I do is a lot better than the image I have in my signature, it was just the case of resolution being too small for me to work with. Other than that 8/10
