How about a watercolor painting kit so he can create his own artwork? You could also consider getting him a set of high-quality watercolor paints, brushes, and paper to improve his painting experience. Alternatively, you could find a local watercolor class or workshop in your area that he could attend and learn new techniques. Additionally, you could get him a book on watercolor painting or a subscription to a watercolor painting magazine to give him some inspiration for his artwork. Whatever you choose, I'm sure he will appreciate a gift that supports his passion for watercolor painting.
Or you can get him a star map with an important date you share.
