Intriguing Mystery Novel Cover Design

Project Status: Novel is complete and ready for launch. Publisher is awaiting a high-resolution sketch to finalize the cover.

Objective
Create a high-resolution character illustration that will be used on the front cover of a novel. This illustration must be based on a rough amateur sketch provided by the author, but redrawn professionally.

Character Description
Main Concept: A dual-identity character.

Primary Identity:
A normal-looking businessman
Outfit: Shirt, tie, jacket
View: From the head down to the midsection
No specific or exaggerated features; meant to appear like a typical professional man

Secondary Identity:
A look-alike of Adolf Hitler
Should evoke Hitler without being an exact replica
Appropriate era-accurate uniform and mustache
Must be distinct but legally and ethically stylized to avoid direct representation

Illustration Details
Format: High-resolution (print-quality, minimum 300 DPI)
Framing: Midsection upward, suitable for use on a book cover
Style: Professional digital illustration based on client's sketch
Use: For the publisher to insert into a pre-designed cover (they handle typography, layout, etc.)

Timeline
ASAP — Publisher is ready to proceed immediately once the sketch is received
Client prefers not to wait for the publisher’s internal illustration team

Additional Notes
No other image references are available besides the client’s own sketch and public imagery (e.g. Google images) for inspiration
Client is interested in working with the illustrator on future projects as well
