Should I change my hair?

Sabine

--I'm the girl with the ribbon and the bandana-- I've been thinking of cutting my hair even shorter, similar to the girls in the other 2 photos. Could I pull it off? Would something else look better? What haircut/style would you choose for me?

EDIT: I know that long hair and/or bangs don't work for me. See for yourselves with this picture from last year:
