I'm sure I could find some of the old paintings or drawings I did in college. I know for a fact my Mom has one hanging in her house somewhere hahaha although these days I'm more proud of my photography and videography than my drawings.
But that's what I love about what you, or other artists, do on the regular. You get that picture in your head and then draw or paint it out. I'm not sure I can do that or I haven't take the time to develop it as a skill. My talent is best applied when I have something to build a new thing from.
So I applaud you in being able to do those things! It's admirable.
