Badge Style

*the design of the badges behind are just a representative guide**

I'm working on 6 badges for an app/service. It will be 6 different animal, each one representing a relational/social characteristic. The app has a flat design without too many icons. so the badges will really stand out. And they represent the only 'gamy' side of the app.

So I'm undecided in going either with a more illustrative style, with potential of animations, or a more static style with the lines.

See attachments for other examples.
The one in yellow is a possibility of creating the badges as 'selected'.
