Sure. A few of the other MOCs I drew used their own mask designs (or at least the design Noupix did for them), and I mimicked that when I did it myself.
This specific topic was basically a spot for me to post the versions I make, in preparation for a possible story (not so much where other people post them). So if you have some bio info (see the link Bokarda responded with), then you can make your MOC's individual info post and I'll link it like I did the others, as well as make a version of them in this style to add on here.
Well, that's already fairly close to the style I'm doing, so I may not actually do him myself. Also, he's go a lot going on in that torso, so if I did make him, it'd be the simplified style I used on the others.
If you have any bio info, just make a page (see Bokarda's link for details) and he'll be another Matoran I can throw into a story.
