Preparing for drawing the details of each level

 After looking for some pictures. I almost confirm what kinds of background should I use. For example,

This picture, I want to desgin a level that the half is under water half is above the water. In each different level, I will design different environment like desert, underground and forest. Because the main story is "Restore" and I will find the fragments of the main item around the world.

Next, I will draw the sketch of details for each level. Then try to run the first demo to check is there anything I need to fix and upgrade.

Here is the new idea of each Level, I will upgrade each level.
