First of all, I guess I'll go with the usual but truthful comment- this is epic.
Second of all, I love the way you draw Bowser and his oh-so-stompable children. It's different than other styles and at the same time, originally striking. The color it glorious- it almost reminds me of stipling, which is pretty hard to master. I also appreciate the realistic way you chose to illustrate Bowser and his boy; for example the almost individual strands of hair or the way his jacket bunches up on his biceps.
This is great stuff, I hope to see more in the future.
Looking at this i have a suggestion, u should draw bowser with black pants and a black leather jacket like hes part of a motor gang or something, that would make him look cool, just saying u should do it
