In this one I added more shading to make it look less flat. I don't even know if you can tell. I also tried the green grass and just wasn't sure about it. I did try to make longer grassy strands. Better?
Ok I tried what you suggested and changed some levels on photoshop. I darkened the whales, added more rim light, and lightened the water. Looking better? I think I like it. Sorry I won't be there for the critique wednesday! Please just add comments here.
