This is great. The shading on the egg white, particularly at the edges, make it feel very 3 dimensional. Same with the highlight on the yolk. You should be very proud of this. I wish I could give constructive critique, but I'm a beginner myself. I don't know how to make you better, but I don't think you should be embarrassed about sharing your stuff. This is a damn fine egg. :)
