I thought the designs looked bizarre at first too, but when I looked through the Kickstarter page I realised he must've spent a lot of time drawing in all the things that fit his Californian theme, so I don't think he's merely making his cards different for the sake of being different. I like that cut-and-paste zine aesthetic, especially with the limited color palette, but as you said this will not appeal to everyone. It's fine, some people didn't like Jackson's beautiful Fed 52 series.
I did offer him some points about making his deck more functional and appealing to cardists and collectors - I hope he takes some of them into consideration.
