The maker for my original suit opened for commissions again today and that sort of got me thinking that I might like a v2 of him at some point, it's been 4 years already since I got him and he definitely shows signs of his age. Go for a smaller head and maybe make him a bit more toony. Of course, since I have other fursuit plans in the works it might be a little while before it happens. For reference, here is the timeline of my fursuits as has happened and is planned:

Jun 2011 - Yuuryuu partial(wolf version)
Jan 2015 - Chirou
July/August 2015 - Yuuryuu(otter version) I have this commissioned and it's scheduled for July completion but who knows exactly when it will arrive.
Probably by the end of 2016 - Yuuryuu(alt color dragon version) I know who I want to commission for it and the basic alternate coloration, but I don't have a ref for him yet.
Sometime after 2016 - Yuuryuu(wolf version) v2 At this point he'll be going on 6 years old. The exact timing is still unknown, but it will depend on how I am with the other 3 and if I actually have a purpose for this suit anymore.

I'm not sure when, if ever, I'll do more with the wolf version because my different suits will be for different things. The problem I'm going to have with him, is that when I go to get ready for version 2 his purpose will be filled by my dragon version suit. I always played the wolf version as a more brooding character, but that's exactly what I want the dragon for. It wouldn't make sense to make him playful because that's what Chirou's for. Maybe I'll have to look at trying something in between, that could work well, but it's tough to play. Maybe by then I'll actually have the experience to pull it off.
