Heraldic Uni WIP

oh wow, he's looking awesome! I love the fur you've sculpted. I personally would go for real hair. It feels like it's a cheat sometimes because it's so easy (and sculpting good looking manes is difficult) but I really like the overall effect of a sculpt with hair- or other added media.
Have you seen the work of Forest Rogers? She has sculpted a couple of beautiful heraldic unicorns you may enjoy.
