We are offering professional quality flats on your comic & illustration if you already have color palette for your pages, we will follow it as reference. If there isn't, we will add color that we think might be suitable for your pages. For layers, we generally separate the layer by character, background, foreground, and other part we think necessary. If you have specific layer request, please let us know. We can provide 2 type of source files: .PSD and .CLIP files. Please don't hesitate to send us message for further discussion.
