This is an alternative method of character progression we can pursue: procedural spells. Start with how the spell is cast, then add the base element. For additional punch, you can add another effect at additional cost.
I tried to get a good angle with approximate scale to what the character would look like in game to get an idea if you could see tell he has a mohawk. Computer's connection to the internet is too slow right now to upload a full turnaround, but these images should give a good idea of what he will look like.
I decided to texture the character to see what he would look like with his new hair. I might change the shape of his head because it looks a little wide when viewing from the front. The hair might be changed a little bit because it seems too cluttered along the sides and back, but I think the spikes part is good.
Since the majority was 1 and 2, I combined them both like Nathan's suggestion. It is now an ice-mohawk. I'm thinking this might be the final look, what does everyone think?
I worked on a few hairstyles for the main character. I wasn't sure if we should go for ice or actual hair and I was trying to keep it fairly simple since it's going to have to match with the hi-res as well. Anyway, these are just a few that I threw together real quickly to get a general direction. Any thoughts on what is working, and what isn't working so I can get a more complete idea?
