So this was interesting
I like this but the one thing that bothered me on this piece was that it was kind of small in size, so one improvment i would like to suggest is make a larger "CANVUS-SIZE" maybe then you can show more of that detail, even throw in a mix of more color aswell, these tips would improve on this greatly, it does need some mix of color though but other then that i thought this was a nice and nifty piece, anyways nice work here.
~~THINGS TO IMPROVE ON~~
Make a larger canvus, show more detail, but mostly add some more color.
