I decided to make some graphical improvements for the upcoming alpha version. This is what I finally got:
Some details are below.
The first thing that needed some enhancement most of all was stickmen appearance. What I wanted to do is to save they cartoon-style look but make the more lively. I added an outline and applied some gradient fiil. Stickmen look mush more appealing now.
This is what was before:
After stickmen appearance was improved it became obvious that player drawings need some enhancement too. I played with a some graphical effects a bit and ended with the sketchy-like style. Drawings now look like some pencil shading was added to them.
Hope drawing would be of better fun in the upcoming alpha version
