A Ring

This is my first attempt of a selective focus still-life. Thank you for

any constructive comments and suggestions!

I guess you were successful with your selective focus, but I don't think this picture really benefits from it.

 

Not a bad idea but in terms of execution I must concur with the above post. The image would be more effective if everything was sharp. Also there seems to be lens flare from the stone. You might want to try to digitally remove it from the shot.
