CT: Rena and Kyuu genets

Woah, first critique in a while. <img src="e.deviantart.net/emoticons/a/a…" width="19" height="19" alt="" title="Sweating a little..."/> Okay, here it goes;

I simply LOVE how you did the shading! It seems absolutely flawless, but I think the contrast could be a little brighter in the picture to make them seem a big more visible.
I love Rena's pose as well as Kyuu's, but for the anatomy, I think Kyuubi's paw could be gripping the side of the branch a bit, since it seems a bit short >>" (Speaking of the tree; it could use a bit of texture, other than that it's fine. <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>)
Other than that I see nothing wrong with the picture and I find it still breathtakingly amazing... Good luck and keep up the good work! <img src="e.deviantart.net/emoticons/l/l…" width="19" height="19" alt="" title="La la la la"/>
