Jason, I only use clean wallpapers, nothing with textures, pictures, photos, anything, maybe a few gradients, if they are delicate and simple enough.
You see I use 2 monitors, and one of them is usually empty, or with small windows, so the wallpaper is staring at me all day, after a while even the simplest one become tiresome and hard to look at.
I loved your recent wallpapers, due to being clean and simple. This one with the concrete, sorry, I can see how well done it is, but, I can't bring myself to use it... 
Any way, great job, really, really great job.
BTW, I use the Faenza icons with the theme Equinox glass, this last icon, should fit in perfectly... 
Totally understand where your coming from I get the same with wall papers all the time!
will work on simple & clean! any colour preference?
