The ZOX Community is a big place with tons of other Zoxers who are willing to help you succeed. If you're not an artist but you have an idea you like to see brought to life, join the ZOX Idea Factory and post your idea for artists to try and create something amazing.
If you're an artist but you don't have access to Photoshop or Illustrator, visit Gimp.org to get free software. If you'd like the real software, Adobe offers free trials of Photoshop and Illustrator through their site.
If your design hasn't been accepted after multiple submissions, please join the ZOX Idea Factory and ask for feedback on what you can do to improve your design.
