That looks pretty darn impressive. You're undercutting what I'd consider your direct competitor, NutSac, with what looks like a quality product. On top of that, your offering a little more versatility with more storage/pocket options and a form factor which could work well for more than just as a disc golf bag.
If your craftmanship and durability prove themselves out, I think you'd have a real winner here! I love small bags. I already have a single and a double NutSac, or I'd probably be ordering one now. Be sure to post if you have some sort of contest/give away...I'd love to put one through its paces!
