Ohh yuck, this is a great abstract! Knowing that this is the Potomac River I see water but in a solidified or rather frozen state. It looks like moulded jelly, slimy blubber or anything other than flowing water. The image inspires me and the presentation is great.
Ps. I like your sense of humour. Ill make sure that my mouse is not going to get it! But I am inspired and like your style. Nice work! Kees
