This harpie was for one of the activities of dA's Creature Week (the wings tutorial) and I also used it for one of the activities of arcade week (line weight tutorial) since I hadn't finished it before. I also challenged myself to practice perspective some more with this one and I rather like how it turned out.
Honestly, I have a harder time with feathered wings so I think a tutorial on those would have been more useful. And after I finished submitting this to the arcade week challenge, I colored the lineart so it'd be more subtle. I also tried out a more broken style of lineart, but I need to practice it more before it comes out looking the way I want it to.
