The tiger photo is quite fascinating, shadow or no shadow!
And sorry, I am the wrong one to ask for help on that one. I don't begin to understand PS... I think my brain is not made for it...
But I know what I enjoy, and I do enjoy this photo of the tiger on the prowl.
Is the forth pic a Stellar Sea Eagle? If so, it's a very rare and BIG bird. About 3 times the size of the American bald eagle. All are good, and the tiger is fine without editing.
nice work. The shadow is easily fixed with the healing brush tool in PS Elements 3, or PS CS2. I used CS2. This was just a quick 15 second try but you can get the idea.
The Before
and the after
grass is one of the harder things to clone because of the texture and shape of the blades. That is why the healing brush is the better tool. What it does it blend and clone at the same time. To make this look like this I made several passes with the healing brush and sampled each pass from a different part of the grass
