CARTOGRAPHY
One of my distinct interests in art has always been in cartography. In addition to the local, small-scale axonometry drawings, I love creating maps of regions, continents, or planets. When it comes to gamedev, I found it especially useful for level design. I can quickly sketch out areas and iterate on the designs. When prototyping in-engine, the process is even more efficient and I can apply proper scale to my maps. Moreover, I can apply critical thinking to natural looking coastlines and borders, urban layouts, underlying geological processes etc.
I believe my cartography skills are useful in gamedev for:
level design
prototyping
minimaps
creating a coherent world
