Elevate a mountain at some point, replace trees with tropical ones - palms and stuff like that , the warcraft fence is probably the ugliest of models in the doodad section, some wildlife I guess can do good to the picture like birds, crabs, fish around the shore etc. Get the ship a bit away from the shore and add some fissures or rocks around it so it would look like it crashed there (increase ship size to 2 perhaps)
I would add some rocks around the shore mostly randomly.
Now it looks like a dead island which is getting burned by the sun itself into the yellowish radiation of oblivion. (damn) +Rep for that.
