I say that this is a great start. Your colors are grand. Your attempt into the unknown are laudable. Your handstitching - minus the insulbrite, of course, is progressing. Triangle points? - they are more difficult with the thickness of potholders but they will improve too. You can't get better and have more tricks up your sleeve until you try. You did! You are on your way! Lots of us have been doing this for a long time, many are new. We all have something to learn. Keep going!
