TheArtDepartment.org and ConceptArt.org have been making art related video tutorials for some time, and are currently having a sale. Sale includes video downloads and streaming classes (pre-recorded), all at $US7.99 each.
Each of the downloadable videos has a trailer on it's product page so you can see what you're buying. I've bought a few of these over the years, and picked up Phil Holland's "Exploring Photography" and it's turning out to be a pretty good watch so far.
Thanks. These look good. I was able to buy them at the sale price even though the banner said 1/8.
