REACT: Collection Sneak Peek

Here are some shirt designs for my company! I plan on screenprinting them myself, woo.
REVIVE is a special edition shirt for Japan; REACT is my signature shirt (obviously), REFRESH is for water/food charities, and RELEAF is for environmental charities. Still working on REPLAY (for youth charity- will have handprints on it for design) and REBUILD (for natural disaster charities). Having a difficult time coming up with a simple design for REBUILD, any ideas? Give me feedback, please!
