I really adore your your art style, and your colouring skills. However if I may say the pose in this drawing is very stiff. Especially since she's playing tennis. D: Other than that, it's still wonderful like others works you do.
Do you practice sketching out the poses a couple of times first? O: I've been told it helps. That, and I'm a little curious as to how you do things. Maybe you should Livestream some time! I'd definitely make time for that!
Yeah, I usually make a few sketches to choose from before I start : P It's a good idea to do a livestream, though I cant concentrate if people is watching XD I've been thinking of making a video of the process though, that would be much possible : D
