Honest its VERY unlikely you can find an artists for free so I say best save up cash for it. I'll say although anime covers do does best on this site, your current cover isnt that bad, albiet it gives a bad boy paranomral romance feel lol . You getting 17 subs only 7 updates for a novel (in fantasy no less) here is pretty impessive. So it is attracting you readers regardless,
You can learn to draw an anime a cover.
You can still try by asking here or on the Tapas discord, stating its unpaid and managing your expectations. Its unlikely you would get a well done high quality anime cover but you may get someone willing.
