Roger, etc., I love the idea. And mostly like the design. It'll probably print. But I have to give my tuppence and point out that the head angle is wonky, especially when you look at the relationship the lower jaw has to it. The horn is at a weird angle. The eye is, as someone mentioned, way too low. And I can't unsee the unicorn 'humping' the rainbow.
Sorry, dude (ette?), I have to be honest, and this needs tweaking to be really effective. Still, as I said, it'll probably print. So, no harm, no foul.
