Thank you so much for your compliments on my art. This means a lot to me and I can only agree that Steemit (especially for artists) is a very supportive and constructive place. Maybe in the future I will write more detailed step-by-step instructions on how I did my work, but I don't want to take the magic out of them either.

I'm glad you started right away, and the thing with the file that can't be opened or displayed is really a cool glitch. Maybe you can delete it with a terminal command. In my first attempts with glitch art I had a similar effect until I came to the conclusion that it was better not to use compressed graphic files (like JPG) but to work with PNG or BMP.

I'm definitely looking forward to seeing any glitch works, you'll come up with. Glitch on!
