The design should be tailored to be printed on a gray T-shirt
(We've already got one T-shirt design: a simple black shirt with logo on the chest, and we want to offer an alternative design. It should look a little more trendy than just a logo t-shirt but still fairly casual).
The less colors used the better: try to use only one or maximum 2 colors.
Front and back printing, nothing on the sleeves though.
Should look modern/contemporary. Nothing with skulls, blood, demons, dragons etc. We'd like anyone to be able to wear it.
Attached are 4 jpeg examples of the direction we'd like to go in.
Also attached is a layered photoshop file containing our logo. You can manipulate or distort the logo but it should be somewhat recognizable.
