Very good layout - no elements are distracting or calling attention to themselves.
Very readable.
Obviously a lot of well thought out work has gone into it.
As for personal preference, I feel that the color saturation is a bit weak.
I would download it and tweak a few color related things - just to see.
I'd probably start with the background - maybe add a touch of texture.
For certain I'd increase the #A3A8D5 purple saturation color a tiny bit.
I'd also play with the #FAFAFA white saturation a tiny bit - maybe try a color shade or two added to it.
I'd like to see a little more visual weight, body and substance achieved through saturation, or texture or maybe even border lines.
Out of all those ideas, the implementation of just ONE of them might achieve a less ghostly look.
As I posted, it is personal preference.
And I like what you've done.
