Looks like terragen, ill be so bold as to say it is.
Maybe if i comment fast enuff you wont submit your "many"
especially if they all resemble this one.
First off, it's a decent scene, but there's nothing going on. You have land, and water, and an incredibly bright sun. One of whom's intensity is far more than it should be, for this scene.
Next the water glare is painfully large, and far too bright. Tone it down, and add some difference to the water as well.
Then there's the plain sky. INCREDIBLY plain. Nothing going on, couple of clouds.
You should really double think what you submit b4 you submit it. Think of what the people want, nobody wants to see the same thing, over, and over again. Next time, try to create a scene that will make the people say "whoa, that's really cool"
