I'm sure almost every fanartist out there has heard of Delia & Sydney, right? Well, this is their site!
Alan Gutierrez's Art Studio - This guy is amazing!!! I just bought one of his Sailor Moon pieces off eBay (if you want to see it, it's one of Eudial under his "Pixie" section in the gallery)!!!
Jupta's Art Studio
This guy's a bit freaky, but he does some great How-To-Draw-SM tutorials! This is actually where I really got the hang of drawing anime, but he's gonna take all the anime stuff off his site soon, so GO, GO, GO!!! Get there quick!!!
Note - Too late. Site's gone... <:*(
This guy is an awesome artist!!! Almost as good as me...^_~
