Well done. I think everyone is afraid of spiral's. I use them consistently & I do like doing portrait's most of all. Well, other than wildlife. I like doing personal portrait's for friends & others too. I would recommend using the spirals for your portrait's, & emphasize the smaller size, the better the outcome. I use mostly 2/0 & 3/0 Flying Dutchmen blades. They have always been great for any type of fret work. Good luck with the spirals & just practice, practice. You will see the improvement as you go along. I know I did. Thanks
