Looks great, but not quite right

I love Sticker Mule. There really hasn't been a time I was displeased. That being said I had a slightly disappointed feeling with these stickers. To be completely fair, they look great and I* (*emphasis added) did approve the proof, BUT the die-cut on my specs was not followed as indicated. Again, it was my oversight on proof approval, but all files had the die-line marked off. I was just kinda bummed that t wasn't how I had envisioned it when I opened the pack. Will anyone else notice? Perhaps and perhaps not. Like I said, they look great. The quality and print resolution is outstanding.
