Blue stripes failed mani

So I usually don't show failed manis but I just love the color of the polish I used and I didn't capture any pictures of it by itself. I attempted to do blue stripes because I was wearing a shirt with blue stripes so I went with the tape method. I had a hard time cutting the tape into strips as well as placing them straight. I used Wet N Wild white creme and Revlon Royal.

Any tips on how I can do this mani better?
