It looks beautiful. I love the contrast between red and blue. The background is also very pretty (did you draw it yourself or is it something you got from google? cause it's pretty enough to be). Your effects are great (care to teach me some?). The only thing i can really find that you could improve on is maybe make it more realistic (if you want to do something like that). I mean, think of how awesome it would look if this was drawn like it would be irl. Also, maybe you can try and make thinner lines? they are kinda distracting, since the rest is made without line or with coloured lines. So thinner lines, maybe not black ones? Though i might not be the best person to tell you these things.
