This is beautiful! Why did you use that tiny brush for the whole thing though? It looks like there are plenty of areas where a bigger brush would have worked just as well and taken less time to fill...
i wasn't actually planning to use such a neurotically small brush, but the unstretched and unprimed canvas had a lot of texture and it was really absorbant. i basically had to scrub the paint into the weave of the fabric so it would be a solid color and wouldn't wrinkle up when it dried. most of the painting is also two or three coats, because like i said the fabric absorbed most of the color on the first layer or two..
so once i got started doing it that way, i just kind of went with it so the whole thing would match. i've started working on a new one now with some more of the same canvas, and i'm trying to figure out how to work the paint the same way (for the larger areas at least) without killing my bigger brushes.
also, it was kind of meditative...when it was unrolled it took up like 90% of my living room floor so i got really into lying there and just zoning out and being totally focused on one little area at a time.
