I'm not sure, quite what you're looking for, but these might help you out some. There are new textures on texturize, and I like to look at iconpraise for inspirations. There are some tutorial-ish stuff on icon_tutorial but I have a ton of random tutorials saved from peoples journals I can look through if you want. You can also find a lot of great tutorials on the Ask the Maker posts at icon_talk. If you're looking for another comm to make icons at, I'd recommend 10in30 which is relatively new, but fairly popular. Also making 10 icons in a month is way easier than 20 in 20! There's a small handful of other pretty active icon making comms too if you're interested. Or whatever other specifics you're interested in I can try to help out?
