I don't know if you only wanted comments on the rapier or on the whole scene. I agree with the comments above about the rapier. Other comments: The stone is too uniform. It appears to have a striated nature to it so I would expect there to be uneven chunks all over. I think you are depicting the sword in the stone. I would expect the sword to be buried deeper into the rock. Although I don't recall the length of a rapier it appears to me that only the tip sticks in. The background is very jagged. Since it is the background I think you could blur it more and therefore the jaggies should disappear. Finally, I am having difficulty with how the scene is lit. I understand you want the rapier to stand out, but how is it the rapier stands out but it has no shadow, the ground surrounding the scene is dark, the closest mountain is dark, yet the furthest is lit?
