The shine on the Blade is perfect. Remember you are useing a sun as your light source so you dont need to darken one side of the circular ring. just the inside of the loop to make it appear smooth and round. The Blade is perfect for example a nice outline makes it appear more 3 Dementional wich is a nice effect. So I will highlight what im talking about and this includes makeing it at a 45 degree angle. Sorry this is a really poor example and I don't blame you if you don't get it And I will freely explain more about it as you get better and better. BTW This knife compared to your first is a very well done and big jump on your work

Edit: lets get the knife done first and than move on to the throwing star and than the sword. In the order of proggress if you will. We don't want to get to far ahead of our existing projects.
