My Meera(brother) and me. Photoshop help?

Would any one mind doing me a favor and photoshopping some backgrounds in these photos? I'd love to surprise him with a slightly better version of this oh so cool photo. And just btw I'm on the left.

Much thanks
Will

what sort of background...are you trying to combine the two into one with a common background, or keep them as 2 seperate pictures?

I was thinking separate to show the difference between light and dark side.

i'll see what i can put together...

i'm not the greatest with photoshop, but then again i only recently began working with it(within this past year) i've been doing alot of various experiments with superimposing images, editing existing images etc....i would love to learn how to do some of the things i've seen done with photoshop...but in any case here is what i came up with...i like the imagery i came up with but i'm not totally satisified with the work itself....i know i can do better with more experience and maybe some training...

I have used Photoshop for a while. I am not great but I do ok. Try taking the pictures again against a white background wall or sheet. This will allow for a much better erasure of the background and sharper superimposed pictures on the new background. Also use a little BLUR or SMUDGE filter to soften the edges of the picture of you.
