Ah, that answered my major question, were you quitting another job to pursue this. Sounds like, No, so go for it!
I had dreams of selling my nature photography for a side income when I moved to Utard, but every joker with a camera has a gallery around here. Same with my woodworking, although I'm still planning on doing that when I retire from the Guv'mint. My third moneymaking hobby, playing music, petered out about a year ago and I can't see playing \"Sweet Home Alabama\" for $75 a night anymore (26 years is enough...).
At least my hobbies return something; I could be playing golf every weekend.![]()
Even if others have galleries...can't you do it as well? Quality will stand out. If it is only a sideline for enjoyment why not throw your work out there and see what happens.
