Original Character Class Cards

In order to propose an idea like this I have to utilize original designs, which is a challenge as I have never been strong with computers/programming.
I am attempting to use GIMP and Inkscape for my initial designs, but may progress to something different based on feedback and suggestions, or personal preference.
To start with, rather than Magic Set Editor, I have tossed together an idea for Character Cards, then will progress to Adventure/Event, Reward, and Creature cards.
See below for the original basic class card designs...
