Different
Okay so this was "DIFFERENT", not something you usually do and more of a real "PAINTING-TYPE" photo of the art you did, rather than something you turn digital or "SCANNED". Did you scan this? I don't see that here. I love the green deep dark background you have here. I always enjoy when you use a background instead of your common go-to of white. I think it adds something different and new, and there is nothing wrong with branching out now and then trying new things like this. I just don't think the main art is something too good, but it is nice. I mean, it is almost like a tattoo design or a "STENCIL" pattern you can use for prints and body art. I think that is what this would be good for here and not too much of a piece for animations or "CHARACTERS". It is a bit abstract in terms of the design and has a dark tone that I do enjoy. It is just different from all the other things you've been doing and I think while it is good to try things, I am not sure I would recommend you do this one over again. Although, I do think it is cool and original, but not something I'd do all the time. The light catching it did make a nice "EMBOSSED" look for this piece and I think if you wanted to do that again that would work, but maybe try to recreate it in a digital means by copying the light and shadows around the design for a crisp more clean look.
~~THINGS TO IMPROVE ON~~
Redo this in a digital way to recreate it and maybe use this for a tattoo or print design.
