nice and smooth. Nice contrast in colours between the flower and the fly. I'm not voting in this challenge, but I'd give this a 6 or 7 I'd say. Good contrast. Very outdoor feel. Focus is on the flower and bee without either taking away from the other.
Only slight criticism is that there appears to be a lot of imperfections on the flower's petals. It'd be nice were this advanced editing to take them away. There's probably nothing you could do in basic. So it's a criticism that can't be helped with the rules... how useless! :)
