Hh- I've always loved Sura's design. The Original will forever and always be my favorite, and V3 looks great as well. V4 is simply outstanding and I really do love the scars. Great job with it.
I would have to agree with Spectrum, but instead of the fur texture for the tan being a bit heavier, I say lighten the texture for the white parts a bit. But of course, that's just me. If you're happy with it, stick with it. The tan looks wonderful as is with its beautiful shading and whatnot. Ijust- helookssoamazing.
