one thing though, you should learn to compose the subject better in the frame. instead of just focusing bang in the centre.
you could always just crop after as well, but i think its best if you compose in the viewfinder first. cropping is a nasty habit!
i have no idea what you want from photography, if you’re just doing this for fun having a laugh and stuff. but if perhaps you want to be a fashion photographer, you don’t need to pay for models.
Two very nice shots with #2 being my favourite. I think if her hair was a little less windswept & some area cropped from the top & left hand side, this would be a really great shot.
