First Two Levels

I've finally finished the first two levels of my game.  The first is a Defense level, with a tutorial, and the second is a Siege level.  I will be able to use these two levels as a template for every other level in my game. I also have decided to name my game Stick Legions, although this could change.  So here it is, I would really appreciate any suggestions or feedback anyone may have.
