Drawn from memory and they can still do about 1000% better then I could XD Drawfree has some awesome videos where they try different drawing challenges out, and they have some anime related ones that are pretty awesome!
They take on Bleach, One Piece and Hunter x Hunter!!
Pretty good, right? I mean they are all artists, but still! It's quite impressive to be able to draw them from memory like this. It's not that easy to do!! Usually, artists use a lot of reference videos
They've also taken on anime breakfast before XD
And lastly, a "how to draw anime" class!
Unfortunately for me their lesson starts with drawing a very realistic face, which is also something I have no idea how to accomplish so I don't think I'll even try XD
