Looks like a lota India Ink and some water color. I did a lot of this in high school and even into college for a time. We managed to incorporate paisley into it, also. We had projects where several students worked on the same piece for weeks on end, each putting a little of themselves into it. They always turned out great. One neat thing we did was to put water down on the canvas, let it dry in certain forced areas and then dropped ink on it and with straws and other apparatus, we made designs, which we later [
after it dried] would turn into artistic renderings. That was really weird, but we were all weird back then.
Your entry is very nice and looking at the other entries, should've won. However, when there aren't any rules and garbage is allowed in, for some reason, garbage always wins out. Some kinda artsy-fartsy hippie attitude thing going on with the creative juices getting better results over real talent.
