I agree with Kelheor, though I will give some constructive feedback.
The opening panel has a lot of text on it. It looks like a newspaper page to me instead of a comic.
I'm not saying that you need to redo anything but instead of putting down a lot of lines my advice would be to show, not tell.
I think your colouring is fine. Your panels can feel a bit crammed together though. Which makes the story hard to follow sometimes. Maybe space out the panels a little bit?
