I do have significant musical training and experience. The prior music training does help, but it mostly just helps me figure out when something is wrong, not how to fix it.
I have three tips:
1. Find a teacher or group you click with. Music instruction is 1:1 because it doesn't scale well, but visual arts you can do with a studio. A teacher will really help since most forms of art are subjective enough that you may not know what you are doing well or poorly and that feedback is very valuable.
2. Do your art every day, even for 15-30 min. Inspiration starts with doing, not the other way around.
3. Try to be better than you were yesterday. Practice things you are bad at, and consciously do projects to improve yourself. There is no competition here except with yourself yesterday.
A final one:
IMO the notion of "talent" for the arts is just how people cope with the fact that the best and brightest in that field did more work than them. I had several friends who were "talented" pianists growing up, several of whom are concert artists now. All of them worked their asses off 5-6 hours a day to become "talented." It took me a while longer, but I eventually became a "talented" harpsichord player in my early 20s. Go at your own pace and don't give up and you will also eventually be "talented."
