Professional question: Asking an Artist to draw a concept months before actual tattoo application.

https://ift.tt/2nqbH8L recently posted about a E.A. Poe concept center around his poem, "The Raven". Specifically the image of the raven perched upon a bust of the greek goddess athena (link to post above).In said post I express a difficulty being able to draw and conceptualize the image myself. I have a tattoo artist in mind but I am wondering if it is professional to approach said artist for a concept months before actually getting tattooed? https://ift.tt/2oaxwcR
