If, like me, you find proper modelling software daunting and feel you have no option but to buy models, please check out Asset Forge! I recently discovered it on itch. You just pick shapes or components, stick them together, extrude and colour.
I don't know how to add texture layers but I am sure it could be done in another app. I am just glad I can now make objects that actually look like something - aside from dung.
