Ideas for another baby quilt

It looks like another baby quilt is required, which is a relief as I'd got totally stuck on other ideas. I flirted with the idea of a dragon, but it's a bit beyond me right now, so I'm playing with a turtle design. Here's what I have so far:



Thoughts, people? I don't really like appliqué, which is why I'm looking at ways of piecing the background. I'm not sure whether the background should be all one fabric or a group of similar fabrics. Some shade of blue for the background, perhaps this fabric (which I'm eyeing up for a backing), I think green for the head, arms and legs, and then greens, red, orange, hot pink and yellow for the shell. Multicoloured border, of course; not necessarily that simple stripe pattern, although it's a start while I work on the actual turtle. I've done a more complex version, though I think I'll wait until I start drawing in real-size before deciding which to go for.

( And here it is )

I've started colouring in the simpler one, and am feeling rather intimidated. I'll keep going, and colour in a more complex one, and maybe they'll look better. I'm sure fabric will look far, far better than me scratching away with pencils.
