Would love to see a full fledged game with that concept! I dig that kind of stuff, it's like Fantasy Life but with more care to the crafting part, maybe it could even use some more action from the player when roughing up the item, or maybe you could also assume the role of the shop keeper and give advice or at least see some clients going in and out of your shop. The art is good but I think it could really use some shading. Other than that, if it was ironed out, it could really be some good and addictive experience!
