Great job on the comp, and good of you in recognizing the need to keep the tree at right - it also anchors the image nicely. Good low angle, and the displaying pose is perfect. Maybe warming it up a bit, or adding a tiny bit of saturation could help liven it up. I might actually crop a bit at left to eliminate the space between tree and edge.
A walk in the woods. Sweet. Conjures up "wild habitat" at a glance. A striking image against the BG. If you could afford it I would try cropping slightly more off the left to see a differant balance. What was your shutter speed on this?
Sorry, missed the shutter speed, 1/160, every other shot was out of focus hand held. I did saturate the bird, but not the background. I may add more red and yellow to liven up the BG though.
I also played with the left side of the crop a bit, but with that tree on the left it looked odd to me being just half a tree trunk leaning over that much. Maybe just my point of view, but I didn't want to put him between two trees for the framing on each side.
Gorgeous environmental image. I don't think I would take anything from the left, that space to the left of the tree there gives it a sense of scale. Great job with the low angle. I might just warm it up a little.
