Front cover for Sherlock Holmes fanfiction book

For a Sherlock Holmes fanfiction book, I need a front-cover illustration of Sherlock Holmes kneeling and reaching down from a large stone block (part of a tomb of an Egyptian goddess - see attached), to simulate someone inscribing on the front of the block -- in the manner of William Blake's famous painting, "William Blake, Ancient of Days" (see attached).
He should be dressed in his usual tweed suit and deerstalker hat, to make it plain that it's him.
Note: AI-generated images are acceptable, but must comply precisely with the posture of the figure in Blake's painting (and with the right number of fingers...). Also, the front of the stone block must figure a series of specific markings (TBA). Since this is virtually impossible to achieve with AI alone, this project requires a genuine artistic illustrator.
