yes, this one and others from his sketchbookā¦ the concept of sketchbook is interesting, because itās opposite with 3d world,wich is often , usually,very definite, āphotolikeā; zbrush give me the idea of using 3d to sketch, (iāve recently posted a drawing, in black and white, very ālooseā),because the incredible āfastā of create with this soft; zgirl, for ex, is an afternoon drawing, but of course balck and white simplify the process! once the mix with pure drawing will be gain, i think zbrush will be a perfect tool, more(a lot more) than with the mix with paintingā¦ and on another side, masking the feet is a fun and classic approach, cose with the feet you loose dynamic; have a look at frazetta, me,n and women always go in the āgroundā, like desappear in the dynamic movement; charest take that often even in quiet (?) compositio,nā¦ Friendly M.
This Travis is a talentuous āStakhanovisteā 
In any case, your interpretation is perfect !
