Aside from the obvious things(like textures), if those are drawers on the bottom left, they could have a means of opening them, like a handle. Also, the rounded things on either side on the top(I don’t know what to call them…the big boards that are almost a quarter of a circle) look a little not-smooth on the edges. Maybe smooth that out a little. Other than that it all depends on the design your going for. If you’re trying for something elegant, obviously you’d need to do a lot more fancy curves and swirlies, but if you’re going for something a little more simple, you’ve done a great job.
