critique wanted How do I make this look better?

[3k932jd22328jdsf 113]

I finally got off my lazy ass to complete my Rainbow Dash comic style art with a background Rainbow speed line thingy but Idk if I want to use the same colors for the Rainbow on both sides for symmetrical balance or complete the other side with the colors of the Rainbow following the ones I have done. Which dl you guys think would look better? And should I add anything after that?

I suggest doing the full rainbow, just to complete it.

Put Fluttershy in it, she makes everything better

First I think you should make the head smaller, and second add the full rainbow. Then it would look awesome!

You should do the full rainbow.
