@Georgios-Christopoulos I think it works as an image ok if the client liked it, but the printed quality depends on the quality and resolution of the photo you took and the resolution and lack of artifacts of the final product after you cropped, edited and saved it. To check this, you should verify in the editing program the dimension in pixels and what phisical size a 300 dpi print would be, also look at it on screen at 100% to notice artifacts. Or, of course, you can just make a print at a size you think right and see how it comes out 🙂

I would make the front characters a little bigger and try to overlap them some.
