If you guys are pulling the "basic pure card" I'll pull something similar...
ZebraStallion:
PTUX with few alterations, and a palette that has been used to death. Basic PTUX.
Zenith:
MC cave rips that can be found in New DoR, few to no palette/graphical alterations. Basic New DoR 2.0 cave. Seen it a LOT in recent Screenshots and SotWs
Angeal:
Basic Pure
CastChaos:
Some graphical and palette alterations, but which get drowned out by rain.
Now, that is a really pessimistic view on the screenshots, and I don't actually think of them that way. But if you guys are pulling the "basic pure" then it should only be fair if you pull the "basic anything" card as well, in which I think CastChaos would be the winner just by his unorthodox screen composition, and some tileset alterations.
Now, let me do an actual review, I'm not voting, as I don't feel like it this week.
ZebraStallion:
The attractiveness of this screen is drowned out by the lines which the screen holds. If you notice, all of the land forms follow a vertical pattern, which is also what the castle follows. The convexity of the mountains could be worked with, let me show a screenshot for what I visualize.

Excuse my limited knowledge on PTUX mountain usage and the low amount of ground detail that I didn't want to bother combo'ing(one thing I dislike PTUX for)
Also, when I made that shot, I lost track of myself, so excuse that last statement I made. Just try to add eye-candy to your shots. Give us something to look at.
Zenith: The screen design is there, as are the graphics. The only reason I can't appreciate this shot is that the graphics are easily found in a tileset.
Angeal: I actually like this one best. But, I say the same here as I say to Zenith.
CastChaos: Clear up the rain. Rain shots have never made good SotW shots. If you submit another shot for SotW, turn off the rain first.
I'm really tired right now, I would've given full reviews... but I can't think straight.
