These aren't easy characters to draw. I thought drawing Blitzo was a struggle, with those massive horns taking up so much space and his inconsistent head design, but the Glam Sisters have MASSIVE hair. It's difficult to fit it into frame and to not have it cover up too much around them.
Initially, I was going to have the sisters facing more towards each other, but then their hair would block each other's faces. I had to awkwardly hide their hair, which was too much trouble, so facing away was easier.
Also, at this point, I still didn't fully understand how their ponytail(?) worked, so it just kind of came out as a weird blob behind them.
