I actually completed the watecolour fish too..
One thing in particular I like about watercolour pencils is the gradient effect that's easy to obtain as you wet the colour , then brush it along to weaken in strength as you go.
If there's "anyone out there" who is IT savvy, I still can't get my nomination icon to work. I have googled how to's and followed their instructions, to no avail. You can email me with some instructions if you can help. I also can't add tangle patterns icon either, so I must be not doing something!!
