Hi,
After reading your brief, I was wondering if you wanted any text or just a graphical design on the t-shirt?
Regards

Just vector graphics please. No need for text. I may add some text later to it.

Thanks,

can you add some examples of design you like (to start in good way)
Thanks you

Here is an example of artwork I like: http://ecoiguana.net/images/sharing/tree-design-crowd.png
