the first is pretty bland as an image. There are sharpness issues on some of the keys, might be because they are backlight? The overall image is a bit flat.
the second image is suffering from alot of extra stuff in the frame that isnt adding to the image, mainly that thing in the wall, the flowers and a bit of pillow. The wall is seriously blown out. The subject matter is boring (because its Nikon haha), its too straight on.
on the plus side, the second one is nice and clear and looks like you tried to use some DOF to blur out the background.
