I would do one of two things. Either crop her and enlarge her in the frame and move her over a touch or make it a more vertical peice and include the feet, also scooting her over a touch. Reasons for 1: Though the dress is nice it is rather plain on the lower half, no swing no billow no texture. The focus is on the face which gets rather lost. Enlarging, to maybe two hand widths below her fingers, will emphasize the face and look and therefore draw you in. Reasons for 2: Although the framework and stance are slightly mucha-esgue the square layout and the cropping of the feet pull away from the strong vertical that is inherant of the figure. It is sort of like the two are fighting against each other. Regardless nice start :)
