Humm gonna have to wait a bit. Try to see with @Jo_J if she's (you're a woman right?) willing to honestly review yours. You might have to wait a week or two if you want me to do it. You'll understand why once I post my first review here.
A little something to begin with.
Your cover picture is awesome! However, the "Patreon/NEOARTCORE" just above the characters bosom is... hum. Yeap, it takes away the charm or it. If you know how to use photoshop try to erase the letters. Should be simple enough to do it cleanly.
Your title is barely visible too. Do keep in mind that human eyes tend to wonder first at the places you see on this picture.
Okay so notice that there are four lines, two horizontals, and two verticals. The dots you see are where they meet. And usually this is where people gaze are naturally attracted to. It's a mathematical law called golden number or something like that (I don't know the correct word in English). In short, it is supposed to define what's beautiful to the human eyes. Don't ask me for further details, is one long-ass explanation.
So, to put it simply you want your title to be written along those lines. Usually the horizontal ones. Take a look at mine.
The catchy word of my title is more or less on top of the first horizontal line. I added to it a golden font, a visible size and voilà! Haha.
Note that there are exceptions to this rule. Some pictures naturally form lines that would catch the eyes. Take a look at the popular painting "The Scream", Edvard Munch.
Do you see the line drawn by the bridge's frame? This is exactly of those exceptions where you could probably write a title on. Tho it would look a bit weird to my opinion. Not the best example.
Anyway, since cover pictures are in majority portrait type images, this is what applies to them.
In marketing, communication, photography, and film production this is common knowledge. They prioritize those zones to have their audiences focus on what they want them to see. Try looking at a professional photographer's work or just at the next movie scene you'll watch and you'll probably see similarities with what I'm telling you.
Hum... I wonder if I really should reveal all my tricks hahaha. Consider this a little favor and a free course on images' structure.
By the way, weren't you the author who condemned my benevolent comment on J_oJ's work "The Bet"? -_- HuMMMMMMMMMMMMMM
