If they're going to cast one person and not another, it's not rejection of your talent, it's just that they want one person and not someone else. As an actor, unfortunately, it's not your job to cast the movie.
I like charcoal drawing a lot. I'm not very good, but I always find myself buying canvases and paints whenever I'm on location, because I always have this ambition to fill the hotel room I'm in and turn it into an art studio.
Sometimes I find myself at three o'clock in the morning painting something and throwing things around and seeing what works. I'd like to properly study fine art. I think it would be quite an interesting endeavor.
