Good point about shadows. Horses are hard to draw but I had a wooden model to help with volumes. Also, looking at diagrams of skeletons of horses helps. I even animated a horse falling over but that's another story ...

There is good cute & bad cute (or fun cute & sleazy cute)...this is good cute :)... but the eye-lashes on the unicorn is cutting it close! ;)

The grass-hadow on the left side could maybe have been a little brighter...it's a bit  too close to the grey-shade of the legs.

Anyways, I'm always impressed when people draw horses (and these are pretty nice)...coz I've always sucked at it! (or never tried hardenough?)
