The leather portion looks just fine. The double strand of chain looks sharp. Nice job!

With all the hardware meeting right in the middle though it looks a little busy. Nothing wrong with showing a little "bling" right there but between the buttons, rivets, triangles, trigger snaps and chain there's quite a bit. I'd suggest drilling out the rivets and choosing between the trigger snaps or the triangles. If you go with the trigger snaps, flip them around and rivet them to the leather and hook your chain to them.

You may even find that you don't need the chain at all. That sporran may not have come with a Sporran Dee on the back to hook the clips to but if you have any leather left over from the strap you can make one very easy with a couple of rivets and D-rings than just hook onto those directly. It may put your sporran at just the right location below the belt.

Great job!
