Card Game - Boost Card Template

My pal Noel and I are huge fans of the makeup & sfx competition show Face Off, so we decided to make a just-for-fun fan cardgame based on it. Boost cards would essentially take on a similar role as Equip Spells in Yu-Gi-Oh; they could be used to augment the stats of either a Contestant or Makeup. The aesthetic of Boosts is based on stained glass. In the first draft, I just went for general stained glass. In the second, I opted to go with stained glass based on stylized waves. And in the third, I made a stained glass tree. Doing those effects was really interesting!
The final image is my first go at the stained glass tree, before I decided on a cool color scheme.
