So many keys... but which is the right one?
And where is the door it unlocks?

Submission for the #Colour-Schemes group's July 2013 challenge.

Vent art of sorts, except it didn't really start off as that.
Lots of stuff going on in my life right now; a lot of things are going to change in the next weeks, possibly months. Unlike represented in this image, though, I found my door, and now I'm looking for the key.

I sort of rushed it a little bit, but I think I still spent about... 6 to 10 hours on this thing in just 1 week. It might not seem like a lot, but it's about the same amount of hours I put into most finished pieces, except condensed in much less time than I'm used to. I usually take upwards from two weeks, but I didn't want to miss the deadline for this month's challenge, so I made sure I didn't stretch it out too much.
There's a lot of mistakes, please don't mind them. I'm just getting a feel for digital still; I'll start getting better as time goes by.

I'm not sure about the amount of detail I put into the fore/midground versus the detail in the background...
I'm experimenting, let me know if this one was a good or bad idea.
