Blather, rinse, repeat

great job on the sketch. It looks amazing colored and the pose is lovely. My only nitpick is that the eyes are not aligned. And this is a mistake even the best artists make when they draw a face that's tilted. A tip: When drawing the eyes of the face, tilt your own face to match the slant of the subject. If you do so AFTER the fact, you'll usually notice one eye is much higher than the other, or bigger, or wrongly placed, etc.

So glad you're loving kung fu. It really is quite fulfilling and challenging, in the best way. About the pushups, though. Talk to me when you have to do pushups on your kunckles on a hardwood floor. ;)
