Go through each link and look through how the authors' presented their art piece. Also you may check their blog. But I will advise to just look at these links and understand their presentation. Your art piece is great, so don't compare your art piece to any of the above authors. I gave you these links to know how to present your art piece, so that you could curated. And if you check these authors blog page, you will see a Twitter or Instagram account to verify them as real artist.

NOTE: Pay attention to their representation and not their skill because yours is good and some of the authors above are digital artist and not sketch artist.

Sorry for the delay had a busy day.
