Are you annoyed with the space above?
Don't be. Humans have this thing where they are insistent on filling space with stuff, usually unnecessary stuff. I bet your garage at home has stuff all over the place stored in it, seems a shame to waste that extra space with just.... space... right!
Well in photography negative space is good and you should use it to give your images drama, movement, feeling and a point of difference. Don't be scared to give your images some space!
