What do you think about it?
Should I color the words?
Maybe "strong" in bloody red and "beautiful" in pink flows into violet like the WTA sign?
I want to print it on an Alu-Dibont for my living room in the dimensions 120cm x 40 cm.
If you´re gonna print it out you´re gonna need to make it at a much higher resolution (at least if you want it to look good) than the image you posted. Professionally printed images such as DVD covers use a DPI (dots per inch, 1 inch = 25.4mm) of 300, or sometimes even 600. If you print it out in 120x40cm at 300dpi it would mean that the image resolution should be 14173x4724. It would probably look ok with a bit smaller resolution, but if you print it out as it is now to that size it will probably look really blurry and not very good at all.
