I really like the goblin shot. Here's another one:
Not Bad, definitely fits the ledger for Alien landscapes. In this case might I add a bit of constructive criticism? I'm not really seeing a subject in this shot, or a center of interest. In all landscape (or street, or portraiture or all photography) it really helps draw interest and visual pleasure to you work if you really think out how all the lines and structure in the shot will lead the viewers eye toward the visual center of the composition. Think of it as a sort of visual crescendo. I think that in wide-angle shooting, and landscape work this is one of the most challenging obstacles to overcome at first. With portraiture it is much more simple, because the subject is always obvious, but in landscape you often have to open your mind a bit and "see" past the overall beauty of the scene, and nail down what it is you wan the viewer to take away from the shot.
