Physical quality is good, need better eye for die cuts

I'm happy with the physical quality of our sticker. However, I should have paid closer attention during the proofing process. My first rendering had very jagged edges for the diecut sticker. My guess is they just take your image file and run it through some software that just spits out the edges as is without an actual human to look at the proof first before sending it to the customer. I had them round off and smooth out the edges when I asked for modifications but my guess is whoever made the change rush it. The right side of the sticker is not uniform with the left side of the sticker and it is noticeable. A word of caution to anyone who orders the diecut stickers, pay close attention to your proof before you approve it.
