Well, I did my first one! I don't think it looks very good but I thought I'd show anyway. I suppose my excuse is that I'm 11.
It's called "Swirls with Meaning" I did it with watercolour pencils.

The picture is awful and doesn't do it justice at all: I took it with my webcam. The colours are bright and the word says "BUT" but my webcam always reverses pictures. Seriously: the card looks WAY better in real life.
