Hi Sportsball,
I really really agree with happy1. I, too, would strongly encourage his interest in visual arts if he likes to build, design and tinker.
Our D prefers to code, rather than build, for her robotics team. She also really enjoys music, math and learning languages. They all work together nicely.
I’m a big fan of nurturing different but complementary pathways for their brains. Plus, he enjoys it! That means a lot 
Good luck to him!
