I can only see a few things that look a little off. The background seems strangely desaturated in comparison to the body coloring, and I think the green is throwing me a little off because there is no other green in the picture. The Chakra I think could do with some blending or less opacity or something, to make it more Chakra looking. Right now it looks kind of like a ring of cut paper. The only other things I can see are some small details like the leg-band and collar which could use shading.
Really good for your first try at digital. It took me a while just to find those things, and even then they are minor. Great job! ~Dattebayo!~
At first, i don't know why did you asked for a critic, this art is already good by itself.
The only things i could say is that you made a nice work with your inkings, a strong hand to make these lines. Your color are very good, and this 'sharp' coloring reminds me of the anime style of colorize, maybe if you add a third tone to each color (a light or a shadow) could fit perfectly to this drawing, increase the size of the strokes outside the character will give you a better result.
You made a good pose here, and the propostions looks okay for me, maybe the proportion between his eyes looks a bit confuse but, it doesn't interfere directly in this art at all.
You also made a nice chromatic composition, leaving a color to cause contrast with the character's colors (up and below).
Well, congratulations mate, you did a great job here
wow, thank you, its great to get some useful tips, i think your right about the colours, it needs more, there should be light coming from the rasengan that would effect the tone of the picture, that i did not add to the image, i will work on my eyes, its hard, i kinda been told that there is one eye gap between the eyes, but it seems different with anime/manga, more practice is needed, again, thank you very much for your crit, made me happy, maybe you could check this other pic out an give me some advice please [link]
