What I love about alternate posters is they're often minimalistic and stronger for it. Saul Bass is clearly an influence on a lot of them. They're striking and often have a good idea behind them or nutshell the film in a simple but strong image. Olly Moss is very good at it, a great designer and I love his work. There are others as well.
Mine feel quite simple but I enjoyed doing them.
A mate of mine had a look at them and while he said he liked them he thought the Furiosa one was the weakest link. Also I realized she really should have her prosthetic arm included since it's such a distinguishing feature of hers.
I had another attempt and while I like the result it doesn't sit as well with the first ones. It's a bit like a cousin to to the others. Anyway, it's just for fun.
