The details on both of the drawings are terrific. Everything from the to the feet is so realistic. I think that the second drawing could use a little bit more detail though. The bird and the lighthouse are greatly drawn, but the sky could be better. Don't get me wrong, this is way better than anything that I ever drew. Also, you chose the right colors and shaded them together perfectly on the feathers of the birds.
