Hello,
Please provide more information about the project, I am interested in coloring these pieces for you.
Will all of them be watermarked? I can use the images given and color them in Photoshop on a separate layer that goes under the drawing and doesn't tamper with the line. However, it depends on what you want to use them for.
The resolution of the linework isn't great and there isn't much I can do about that. I can have them ready in 5 days or less. I will color one piece free of charge to provide an example if you want. Let me know.
Regards,
Diana Graur
