Thanks for the comments. Yeah unfortunately I submitted the wrong one. The one I should have submitted had more DOF. And I thought I had the glass clean, apparently not. Thanks.
I do remember that pleasing smear of paint in art class - I always like how the colors ran together. This subject is a good idea for the challenge. It would work better with less black more color and having all of the paint in focus.
interresting abstract theme, but something is a bit odd... as I look at this, I am expecting a two dimensional shot but the depth of field/focus seems to go from sharp to soft moving up the frame... it just seems odd...
