It's interesting. Not particularly my cup of tea, way too much post processing, but for what it is, I think it looks nice. I do think a ligher foreground would help out some.
I think the owl needs more detail showing, it looks like it should be the focal point to me and its not. If it wasn't for the halo around it, it would be lost (and maybe removing the halo from around the grass as I think its a little distracting).
Just in time for Halloween, eh? Its a little strange... not quite sure what to think about it. Owl should be either a solid black or include more detail.
