I would say very well done for your first sporran. (You should have seen Freelander Sporran's first prototype! ) It is simple and will go nicely with a brown day wear outfit.

I would suggest a slight alteration and not having the flap come to a sharp point. If it were mine I would slightly round it. To me that sharp angle stands out from as not blending in with the other soft curves of the sporran.

A decorative button would look nice but visually isn't essential.

Well done and enjoy the games make sure to bug...err shake Todd's hand at the Clan Cumming tent.

Cheers
