Most are easy for me the only ones I can't are Geoff, Cody, Justin, Zeke, Harold, Chris, Chef, Eva, Beth, Sadie and Sadie.Well I haven't tried Sadie, Eva, Zeke, Chef.
The easiest for me: Cody (I used to draw him pretty often, so I've gotten a lot of practice with him.) Courtney (I've practiced drawing her, and I also think that she's 全体, 全体的です an easy character to draw.)
Hardest for me: Ezekiel (His head shape and hair are really hard for me to draw.) Owen (His size, head shape and hair are awfully hard for me.) Lindsay (I've gotten pretty good at drawing her, but I still mess up on her head shape.)
