Great work on the poses and expressions - they feel really full of life and character! I like how abstract and colorful the background is but it doesn't distract at all!

You captured the expression so well xD - the thumbnail made me curious enough to click through and you nailed it!
The only thing I'd suggest is maybe try a rolled ankle position, rather than a sharp turn? The sharp angle is very clear but it also looks like a much more severe ouch.

Loving the vibrant color and super clean line edges!!
