you might want to try and shoot until you can keep more than 3 pics, otherwise you won't even know what you want or what you like
ask yourself what you want to get out of a picture, ask yourself why you're shooting what you're shooting, why are you doing it in a particular way
my point is that you should be a bit more aware of what is going on in youe photography and that way you'll have a way to orient yourself towards things and pics that you like more yourself, if that makes any sense
for example, think about why you took the 3 pics that you posted here, and the difference between them; if you showed them to some of your friends, what reaction would you hope for?
