I think it's the combination of the relatively normal earth and water with the red sky that throws me -- by the time I got to coloring the sky, I wasn't thinking about love anymore so it reads more as "red sky at morning, sailors take warning" to me, or maybe just blood. Also the dark blue rain slanting insistently against the red backdrop is kind of... it is too uniformly spread in contrast to the weirdly spaced-apart trees, and then that combined with the clouds being colored in rather than left blank and fluffy creates (for me, anyway) a fainter version of the ominous "I am closing off all your options" effect of my classic depression landscapes.

I think what really gets me about the bottom sketch (aside from the way the interior contour lines on the mountains refuse to line up in a consistently intelligible pattern and the utter barrenness of the landscape -- no life whatsoever) is that I drew a barrier in the sky, after I'd already broken it up and trapped it into tiny fragments. The symbolism is not subtle. And yet I drew that damned picture over and over all through my teens and nearly until my 21st birthday without realizing it was a metaphor for the inside of my head. O_o
