After a few attempts I was able to compose a scene of how I though the game would (or should :)) look like.  The initial image was very much the flat style I was looking for but I felt it needed a little “oomph” so took that into photoshop and played around a little to try and emulate some glow and blur effects to add a little depth.  I hope we are able to achieve something in this direction with Unity 3D, or at least something close.  Probably with some Pro effects or other shaders.  Let’s hope!
