I still doubt that. Your opinion of anything you produce has nothing to do with the opinion that another person arrives at when interacting with said piece. When was the last time you did something that would be considered “general arts”? I used to wrestle with a similar self evaluation then I started doing daily sketches of small items in my house. 20-30 mins with 1x pencil, 1x pen, 1x eraser. I also write little notes about the experience. It’s a confronting exercise on many levels. Daily visual journaling. I am 100% sure you could challenge your self estimation, for the better by simply being curious. All the best!

Oh, that might be. But my interest in arts is pretty low. Maybe that's the point.
