Not bad! Looks like the red went on a bit thick in some areas - you can see some brush strokes and whatnot.
With what you have, the things that come to mind is finding a way to break up the large swaths of red. Those lines between the panels are prime candidates for some contrast. Same, too, are those "bumps" you see on the wings and fins - I'd consider setting them off as some kind of light, rather than just a nodule in the wing.
