Well done!
I like the selective colours in this one. Makes the bee in focus pop out, and it is so well in focus! Wow.
And yes, you better leave the blurred one as black and white as the rest of your background, it would not work well as a second "coloured" one here, I think.
maybe colour the bee in in the background. but dont make him stand out as much as the bee up front, make it look like the focus if you know what i mean..
