Can I suggest making it a little more dirty ?
For example the area's where ground meets grass are very sharp, I did a 3D demo a few years back with the same problem and the person I did it for asked me to make it look less fake, I had no idea what he was talking about but in the end I just made look a little more messy like real life.
Instead of a nice flat line between grass and tile, I had some parts where the grass grew over the tile so it was no longer a nice perfectly cut border..
Just a thought, it looks nice and shiny for sure.
