You do your work on a laptop, Wolfie? I take my hat off to you! It occurred to me that what I had been trying to say in my own clumsy fashion is that you spend ages making the character, don't skimp on the promo renders. Spend days on them showing as much as you can... I was looking at promos yesterday that had renders in Poser and in an 'external renderer' (unbiased). Really really got a good idea of the potential of the mesh and textures, regardless of whether I have that renderer. Maybe see if you can collaborate on promo renders?

As to the character, looking at the images you posted... it's the mouth. Accurate and realistic lines for sure, I just don't like them. Aesthetic preference.
