First Digital Painting

Not a bad start! I really like the work on the hair and bikini. That seemed to be the areas you brush work looked more confident. Her skin however seems like it would have benefitted from a lower opacity on the brush work.
But overall good start, but it's not the painting that is an issue to me, it's your knowledge of anatomy and how light and shadows work.
The way the left arm is bent in a unnatural position and the right leg disappearing really distract the eye.

trust me because I do the same exact thing from time to time lol
