Looks like a pro to me. You did you usual awesome job! There will come a day when spirals are just another tool in the box and you will be as comfortable using that tool as any other. I love spirals for many things, but they are just another size, type of blade, just like flat blades only different.... And, I say with a little practice you can cut just as straight a line with a spiral and you can with a flat blade... The only thing I have not been able to do with a spiral is make sharp pointed corners.... well, Charles Dearing (who says he has never used a flat blade) says he can and told how in something I watched several years ago, but doing as he says I am only successful about 30% or less of the time.
