I like this drawing overall as the anatomy is mostly right and the colors, shading, & background look really nice but there are some flaws holding it back. Most obviously is that the arms should be a bit longer (The hands should be down by the start of the legs), the muscle joints on the arm look reversed, and the hands look super off since the fingers are a bit too long. Also, the character is leaning quite a bit, so to catch that flip the canvas occasionally.
Other than that this is a solid effort.
