for me, I prefer the blank background, as I'm not sure what the logic of the background is; I'd even suggest the traffic light texture doesn't quite belong in your lo-fi world; I'd try flat, blanket colour for your background if you want a colour in there.
Depends which colour of blanket for it to be blanket colour - no? :P I agree, the background does seem too distracting
