I like the lower left one because of the unusual alien-looking appearance.

for pure aesthetics, the upper right, though the lower left has its appeal, maybe some altering of textures to reduce the mismatch in the primary structural elements.
the lower right reminds me of an episode an episode or two of STNG. the upper left not sure.....

Upper right, but nice work on all of them really!
