Creating backgrounds

I have created a couple of backgrounds for my platformer/sidescroller game.

This first one is very basic as it will only be used for the tutorial level of the game.

But after the basic tutorial level is done the player will then drop down into a dungeon which is the scenery that they will be seeing a lot more of.

I used a few reference images for lighting effects and still went for a basic brickwork design, the way I have made it is so that If I want to change the scenery a bit it would be more like my tile sets so I can add moss of lava between bricks.
