Unexpected Keeper and playing in PhotoShop

Well I was out and about taking pictures with my lovely girlfriend the other day and for some reason I ended up with this weird picture. She hates having her picture taking (reason: I belong on the other side of a camera) and I got this shot just out of pure fun and for no real reason what so ever.
Then I noticed some potential in it... search for a suiting background and came up with these guys. What do you think? Something to try again yet with planning and better prepared (clothing\props maybe and such forth).
Background image captured by Hikaru Inoue optained from here.

Very interesting! Perhaps crop it from the left somewhat?

From the left? I was leaning more towards from the right but I think I'll try cropping from both ends maybe.

Thanks

EDIT: Tighter crop better?

Very strong! Excellent!
