The Empty Child Revisited - Step 1 - The Background.

I'm back again! Here is what I have so far for The Empty Child - just a background, but the Union Flag superimposed on St Paul's inspired me to continue with this cover. I don't want to rush into this like I usually do, so looking for critique and advice on where to go next. I will be looking for pictures of the child, the Doctor, and Jack. Maybe Nancy as well.
