Page 3 of my Sonic character studies was devoted to the Sol Zone, and its two most well-known inhabitants, Blaze the cat and Marine the raccoon. I'm really pleased with how the ones of Marine turned out.
As for the little sequential doodles with Shadow and Blaze-- eh, don't ask me. The night before I drew these, I saw Hellboy on TV, and I thought the reference fit really well. XD
