One thing I really like about this pattern (dinosaur) is you can completely change the look by changing the fabrics. I can see it in pink with hot pink spikes, medium or dark pink body, light pink head, feet and tail.
If you did it in silver and make the spikes into more of a sale fin, the tail into a fish tail, and the feet compined into two smaller under fins you could make a rainbow fish. Quilt it to look like scales.
