This isn't what I expected from a professional at all. Nice painting technique but I’m kinda unsure how you let slide such obvious anatomy mistakes. For starters, the neck is off-center, not at all aligned in between the shoulders. Taking that into consideration, her shoulders are overly broad. Her left breast fuses with her arm, her left hand is too big and the elbow is way too pointy – she could stab someone with that thing. Not to mention her right eye, which is off to the side, not aligned with the angle of her head at all. Nice try, but you have a long way to go in terms of anatomy.
As for the colors, everything looks muddy and dead. The only thing that gives her life is the red on her nose and lips. Blurring other parts to bring attention to the main point of interest (in this case, her face) is good but you got close to overdoing it. For the background you used almost the same color as her skin, which doesn’t make her stand out at all, and that is a problem.
