Well, what is there to say. I've been "active" here for nearly 5 years. I guess I'm long overdue for a ref sheet for my fursona, huh?
And I knew for sometime who I would turn to for it if/when he opened for commissions, SkaterYena. He has few squirrel characters, though more toonish in the The Nut Job style. So I asked. At the time he wasn't ready to do commissions, but when he was, he got back to me. I'm proud to say I'm his first customer.
He was open to giving a more feral look a shot compared to his normal comfort zone. He was very communicative on every step of the process and got me to think on things I hadn't thought of for Aldin.
Overall, I'm quite happy with this.
Be forewarned, some of his work is NSFW. But if you like what you see, contact him about a commission.
Update 12/27/17: minor tweak to face/muzzle thanks to Skater.
