I like the overall Sig; I have a different style than this, I prefer a more smoother style as opposed to it being sharpened. The sig looks great imo, I just wouldn't have used a lot of sharpening on this. But again, thats just my personal preference, keep it up though!
I do like some of the colors I think the main focus looks lost and the green shouldn't be there at all imo I am no expert just what my eyes are telling me.
