JPG + AI + FLA + PSD
This is something like a T-shirt for Designers.
JPG, AI, FLA, PSD are common formats for designers. I just mess around with vectors and come out with this design.
Added Jap characters in the design to spice up the style.
*The t-shirt is white in color, and the design uses white too. So i duno whether to count the white as a color used. But anyway, i counted it as used as well. Since i just use few colors in this design.
