Okay
I think this one right here is pretty good but another piece of art we've already seen from you is okay, but I would like to see more different things other than Luffy. Don't get me wrong, each time you do this it is nice, but I am thinking you should move on now to something a bit newer. I do love the power being his expression and he seems more animated than before, maybe that is just because he is closer and more upfront compared to the first piece you did. The black background with sparks of color and textures around him, almost like a glow, was nice to see and something you often do well with your work. I think overall I did enjoy this piece and to end my review I will say keep this great work up but try to expand your ideas.
~~THINGS TO IMPROVE ON~~
As stated above, just need something that isn't Luffy.
