Wrinkly paper is wrinkly. I tried my best at straightening it.. Painting on this paper was very hard. For some reason it didn't get much color from it's coffee 'bath', but at the same time was very hard to paint on, as if the paper was filled up with pigment, hence the sloppiness in certain parts :>. I still like it though.

If I'm having trouble with wrinkled paper, what always works for me is to fill a hot water bottle with hot water and place it on top of the dry painting, (with a thin sheet of paper in-between the hot water bottle and the painting). The heat and weight of the hot water bottle flattens the wrinkled paper perfectly.
That's an awesome technique! All those seemingly different medias made a really nice harmonious piece of art. I don't think that it's sloppy It looks a little bit creepy, even this kind of clawed girl's hand. Love the earthy tones that you used.
