Android Jones is also one of my favorite artists. My avatar is one of his pieces.

Ha! So it is. I rarely pay attention to people's sets, so I never looked properly at yours to notice that it was actually one of his pieces. (Though, I do recognize it now.) 

[quote=Brand]The biggest problem I have with his videos, even the ones he lables "tutorials" is they are sped up far too much to follow along or study.[/quote]

I have several of his videos and they're interesting to watch. (They're really what turned me on to using Corel Painter, rather than Photoshop.) I have no trouble following along to them -- even though they're sped up, you can still get the gist of what he's doing. (With videos like that it's more about watching their technique and their general process. It's really rare you'll find a 'tutorial' video done in real time so that you can follow along with them. I have yet to really come across any like that in my own research at least.) I mostly enjoy just listening to him talk about what he's doing and about the choices he's making. Though, since I don't really tend to emulate his style, I suppose a more generic overview of his work suits my purposes fine, rather than doing any in-depth studies based off it.

[quote=Brand]Can you also be more specific as to which parts of the face it looks like I'm guessing on?[/quote]

I mostly notice issues in the top half of the heads. Your placement of cheekbones (zygomatic arch area) up through the forehead/temples. Your cheekbones always vary slightly in each face (so they're uneven) or they'll be placed too high. (Where the bone structure would be virtually impossible in a real face.) If you do some studies of skulls from various angles it should straighten the issue out fairly quickly. It's a subtle problem, but definitely one that seems to be a recurring issue in the pieces you've posted.
