Nice Work!
.
Just as suggestion,
i like(d) smooth, even background texture to not distract from main subject matter focus.
i find light blue fairly neutral, as like used in still image transfers (but green bg in video)
>>light blue towel very easy, blue tarp a little strong(color)
>>subject(s) need to contrast to bg, even if blue/just different shade
Closer context, even if 'crop' pics helps focus clarity as well, for larger 'splash' of subject on page/larger drawing to focus
.

.
Also, have gotten in habit of sig on work, as far as authorship, but then contiguous thoughts (hopefully) with other works so signed.
(wish had done/layed that seed long ago in pic above)
More of an anti-plagiarism minder too, but also very conspicuous to such intent if small discrete sig is removed.
>>If getting collection such as Agent Smith's, would ref site/advertise where rest of gold is
>>works for more views and flagging as even more egregious intent if that were removed.
.
edit: i think the one called XaraX; found similar pattern of presentation of even bg, bright, full, close, contrasting subject matter.

and would imagine if someone used it (as i just did) he'd like it better 'tagged', tag preserved and as service shows what thoughts this modeling is a part of(author's view as a linked subset and breadth of view offered)
