so, you prefer everything to be all dark and mysterious? that is fine, but see if you can play around with the light and dark a little more, perhaps add some color in there as well. for that, try on some of your own images.
these are really dark. yeah i agree with dwayne, i think it would be cool to enhance some of the colors or add a tiny bit of light somewhere to make it seem even darker elsewhere.
You're a regular dark soul, aren't you?
