I can't see the first, but I have a few recommendations for the second.
From a screener's point of view, 1600 pixel wide shots are very hard to accept. They instantly review flaws that the small shots don't.
The acception rate for 1600 pixels wide is far lower than the other resolutions!
The odds are stacked up against you unless the shot is perfect!
I highly recommend that you don't upload 1600 pixels wide whatsoever.
If you do, reserve it for very special shots where detail might be required.
Other than that, I'm viewing the photo on the LCD
screen at work, so it might look worse than it really is (I screen on a really HUGE Sony Trinitron at home - LCD
screens are not very good for editing or screening in my opinion).
The res is too large on this monitor for me to see if it's centred or not... (I also screen at 1600x1200). But I can see that the windows are a bit blurry and the nose is a bit blurry.
Borderline for 1600 pixels. But you would have this accepted at 1200 x 800 for example.
Decrease your upload res, and you rejection rate will drop significantly.
Respected users.... If my replies are useful, then by all means...
