I'm not 100% happy with these but as a first attempt I think they could be worse. I want to upload them anyway to make a point that I didnt even consider in the design process. 

 

 When i was designing these they looked pretty damn good... (from my laptop screen) it wasn't until uploading them and looking on a different device I noticed how painfully bright the green was. My moral of the story is, check your display settings and calibrate your screen.
