Your style is awesome! ^ ^
this is actually a really interesting piece, you did an awesome job putting depth into the picture despite the fact that you were limited with black and white without the possibility greyscale, which is difficult to accomplish so i'm quite impressed.
Also, i like how deeply you described and explained the painting and conceptual side of it, it adds an extra dimension to this that's quite nice. Great work
Although a limited palette of colors, you've managed to capture a lot in this picture. The color choices do bring into mind cave paintings. I think it accomplished what you've aimed for in this picture (based on what you said in the description). It causes me to think back to the "age of the dinosaurs", when these guys roamed the earth. Great job, and do keep up the great work.
