Something fishy....
I just finished this poster - experimenting with a new technique, which I have christened "Horrible Mishmash Of a Bunch of Art Supplies That Probably Should Never Be Used Together". Catchy, huh? I suppose the acronym for that is HMOBASTPSNBUT, which ironically is almost exactly the sort of frustrated sputtering noise I made while trying to get this to work. I did an underpainting with gouache, colored pencil and collage, coated the whole thing with spray-on acrylic sealant, and then used oils over the top of everything. Thanks to SAMADHI CHANDRA for posing as my mermaid model - I don't think I've really done you justice here, but the painting's heading your way!
