Planing soft toy for a baby, I'd appreciate some feedback

That's my drawing for a sea-horse soft toy for a -not-so-newborn baby of a friend. I'd love to hear your opinions.

I'm thinking of using two or three different fabrics and satin tags for the fins, perhaps some yarn as "hair".

I know seahorses have spikes and baby would love them, but I doubt I can realistically tackle that level of sewing detail.

What do you think about the overall shape and size? Or anything else I haven't thought of?
