welcome to
RP, iiphotography.

i like your composition and she definitely has a 'look'. however, the lighting is somewhat dull. you want her to stand out and lighting is the key. a tighter crop might be good also, but not as important as the lighting in this case.
i'm attaching just one such possibility and even mine i'm not completely happy with, but shld give an idea what i mean.
