The visuals feel roughed in, not finished quite like other things. The coloring and details look very flat, one dimensional. Animations while riding it are stiff too for the player atop. It's missing a sense of fluidity and grace, both which are important regarding a unicorn.

I'd like to see the animations and coloring improved, and perhaps something subtle added to give a bit more of that air of wonder and beauty attributed to unicorns. Maybe a thin subtle glow to the horn or hooves perhaps, or a unique hoof fall sound. It doesn't have to be trailing giant rainbows behind it, but something to better represent it as a unicorn.
