its personal preference, but i would also suggest to NOT put the green background as you did in the 2nd picture. the problem is that you lose the depth of field, which is what would make your great picture more impactful. i'd love to see a blurry background - unless its a background that you don't want viewers to see.
i'm a fan of keeping the pictures as natural as possible. all flaws and nuances are what make each picture unique and individualized. if you can, i'd really like to see you post the originals minus the photoshop job. would be interesting to see what you captured.
sorry if i am suggesting too much.
