ATR-Wonderbolts Academy Edition- Down Time colored

this was for Equestria Daily's Artist Training Grounds - Wonderbolts Academy Edition but i didnt finish coloring it in time. im still learning the program (GIMP) so its still a little slopy and unfortunalty GIMP doesent have all the tools PS does so its a bit harder to use any way. in this picture i have Twister Chaser reading in her down time at the Academy. hope you all enjoy it and comment if you have any advice for me that would be mutch apeceated.
