Cool that there's a store now. I'd buy a poster, except for some reason they refuse to stay on our walls.
Shirt will be mine in short time, be it my own money or the holidays.
That said, the pinwheel got me wanting to go back through Derelict, and reading it like that, one can really appreciate what a fine comic you're making. I was unhappy that Parallel Dementia was ending without resolution (not that I'm one with a right to complain), but as Derelict has shaped up and shown its colors, and in looking back and seeing many hints to things we have a better understanding of now with the world, fog, gargoyles, et cetera, I think you made the right call moving to another project.
I also think the top of page 48
would make a good shirt. I feel like you did the wind turbine as a rusted version of the pinwheel visual motif.
Anyway, great work, man.
