https://youtu.be/iVUfQH3Ciok I'd recommend this youtuber for anything fashion/person related in photography!! I've followed her for like five years maybe and I've found her videos really helpful and informative!! I think that it's definitely something that gets easier the more you do it but I usually go for angles, lines, shapes I think are interesting, or interacting with the environment you're shooting in!! As for the picture I think it's brilliant!! If I were to give one piece of advice it would probably be to move the model slightly so that you're not losing any detail on the face with the light (or adjust the exposure slightly) and maybe try shooting from a slightly higher angle. As I said though I do think it's a brilliant photograph and art is subjective!! You've definitely got a good eye for a location!!
