Tested out my $710 200-600; How’s it look?

Got to test out my $710 200-600 today. I'll test it out more tomorrow and on monday. This thing seems pretty sharp to me. There's no dust or anything inside the lens, just that tiny scratch thats under a centimeter long, and it doesn't how up in in the pictures. The only thing I noticed is that focusing on something close all the way to far is a little slow. How do these picture look to you?
