I like to stick with low-poly, PBR models because, simply, they sell. I have fits and spurts as to what genre I model in, usually medieval stuff but of late, sci-fi. Hasn't appeared to have made much difference apart from now I get sales in sci-fi as well as medieval lol.
I do something similar with my website: https://stgbooks.blogspot.com/
Either way, good luck. I wish you all the best in your endeavour.
