You're welcome! That's what I'm currently working on, lol. So far, I feel like I learned a lot and found a process that works for me. I think vertex color will stay my primary method, but I might go back and look at things that might benefit from having an actual texture. Hopefully it'll be ready to publish in March π€πΎ.
One more recommendation for people starting blender is to check out the YouTube channel by Grant Abbitt. He has a ton of beginner tutorial playlists that focus on teaching the tools in a way that I think translates well for those of us that started with primatives and he keeps it low poly. He challenges you to try to build the item first, then he shows you how he approaches building it.
