Thanks so much, everyone, for your thoughtful and detailed responses. To answer Lobo3433's question, I wish to design:

1. Science fictional armour and spacesuits, especially similar to those in the classic Micronauts comics (recognizing that I can't steal the IP, of course)
2. Robots
3. SF vehicles, especially spaceships
4. Modern Senegalese and Nigerian clothing, and ancient Egyptian and Sudanese clothing
5. Aliens (humanoid and other)
6. African hair assets (the best new ones are all for G3/G8, alas).


Thanks for whatever guidance or links to paid & free tutorials you can share.
