This was fine. The rocks have the right amount of gray to make it look like coastal rocks (Seeing as that's what you're going for in the background). Also the grass' shading is fine, it looks wet, kinda like seaweed or something. The shadowy part you have there is great too.
It's hard to decide on what to choose seeing as how everyone has different opinions, sometimes it's not the best idea to ALWAYS go with what one says, you have to decide for yourself sometimes. If you like it, keep it. The decision is yours, but this one in particular has my vote.
