The Little Mermaid - Watercolour Test

Last night I thought I'd get the paints out as it has been ages since I last worked with them. The base of this image is watercolour and pen, and then I took it in to Photoshop to work on it some more.

"We must not imagine that there is nothing at the bottom of the sea but bare yellow sand. No, indeed; the most singular flowers and plants grow there; the leaves and stems of which are so pliant, that the slightest agitation of the water causes them to stir as if they had life. Fishes, both large and small, glide between the branches, as birds fly among the trees here upon land."
Hans Christian Andersen, The Little Mermaid
