Learning to paint shells... I struggled with the colors and my outside edge lines are not crisp. Not sure what I am doing wrong or how to correct it so I get crisp edges. I found myself tracing the outline with paint, which made it worse!  My worst one was shell-1. I was so frustrated that I tried to wing it on my own to see if I could do, thus the Shell-1-different shell.  My favorite was shell 2.  I think it looks the best of the three.  I messed up the shadow on shell-3.
