Here's how I clean up my thumbnails sketches done on paper (15cm squared in this case). I heavily used reference here (gathered beforehand as I couldn't do it during video) because I need some Swedish animals and plants as a base for this project. They'll be heavily distorted, but I still need to consider what kind of base structures I have to work with. The rider is an altered version of Necron 99 from "Wizards" (a 1977 postapoc Ralph Bakshi movie which might have vague ties to early RPGs).
I stopped a bit early as I can't record for long with my drive space. Might continue on this sheet now.
Unfortunately Youtube made the video 360p for me, not sure what's up with that as it should be 480 at least.
Animals: Svart Skogssnigel, Hästmyra, Lockespindel, Harkrank, Öronmanet.
The tech level in Mutant is Musket era so I made a study of that. The other rifle is from Wizards.
