I was tempted to say that myself (bet everyone else was too). So....now that the lid is off the Critique Can-o-Worms, I'll add that the backside needs work as well. Just skiving and/or sanding would have produced a more finished look. From there you could have stained and/or lined (suede would be my preference). Burnishing the backside is not an option as it would be too slick and your phone would inadvertently slip out. Yeah, you'll have to take it apart to do that, but then you have an opportunity to fix any stitching errors. :-) Or you can just leave it as is (I would) and make another one. Has anyone here ever been 100% satisfied with a completed project of their own?
Be sure to hang on to this first project as your personal HRP (Humility Reference Point) and keep out for public display in your workshop. Right now it's the most beautiful thing you've ever seen and you're proud of it (and rightly so). A year from now you'll wonder why you thought it was so wonderful. Two years from now you will cringe every time you look at it. Three years from now you'll want to throw it away. Five years from now (if it's still around) it will be a quaint anachronism of where you started, how much you've you grown, and that every project could have been better.
Btw, just curious, are you a Smithy?
