Hmmm not sure I have a suggestion of an artist specifically, but why not find a pose stand or something and make a multiple angle reference sheet for Alex? Any artist worth their salt should do a good job with a multiple angle reference sheet to work from.

Depends. How realistic/toony do you want it?

Less toony than Saturday morning cartoons, less realistic than hyperrealistic painting.

Lookin' for someone who can draw dynamic-looking fur/fluff/hair. n.n

Hmm... All of the people I can think to recommend are closed for commissions. If you're willing to wait, though...  silverfox5213  nekoyoukaii  ruaidri  anakuro  arctic-Sekai might be worth looking into, based on the style I think you'd be going for. I've no idea what they're like as far as commissions go, though.

Some more people worth looking into (most are closed; again, looking just at style)...  Strype  silentravyn  nagi-wolf  jc  superboll
