Do you think it would improve a lot if you clone the good antena and put it on the other one? Its good the way it is but I think cloning the other antena would be a tad better
I like everything but the composition. It really bugs me (no pun intended) to have more space behind the subject than in front of it....it is almost centered with him a little more toward the left side. I would have framed this with butterfly and right edge of the center portion of the flower both on the right edge of the screen with more space left in front of him. I do like the vertical placement of everything though and colors and exposure seem good to me.
I see that you didn't ask for c&c so I apologize if the above was unwanted.
I agree with everything Nate said. I do belive that the lighting is extremely unfortunate, however. If you could have gotten the sun about 45 degrees more to the left, opposed to straight down, the lighting would have been waay more dynamic. But hey, you do what you can with what you have, right? Nice shot.
