Roaring Bull,
I agree with Rich your items look sturdy and many of them look like someone sewed them up for him/her self - which is how many original pouches were made. I also agree some of your designs are more for a different crowd.
Another way to improve the "finished look" of your work is to make the stitches more uniform. I wish to HEAVEN someone had told me about this book when I first started sewing up leather pouches and things back in the early 1970's. (Oops, well after researching I find it wasn't written till 1977) Some things I guessed into doing right, but this book opened my eyes so much it was amazing. It could be the best $12.00 you have spent for quite a while.
THE ART OF HAND SEWING LEATHER BY AL STOHLMAN
http://www.ecrater.com/product.php?pid=5799891Al and Ann Stohlman also wrote books on making leather case items, etc.
If you are interested in the subject of any of their books, you will get MORE than your money's worth from them. Since most of us can't haunt a real saddlemaker's or cordwainer's shop, these books are the next best thing.
Another thing you might want to do on some of the heavier leathers is to burnish the edges of the leather. This can be done with a variety of tools and trust me you will wind up trying most as you continue.
The important thing is to keep trying to make your next piece look better than your last in every detail.
