Are you looking to hire someone professional on Fiverr or somewhere?
We talked with my artist and we actually decided that we will be working on another cover. @darthmongoose wrote a very nice analysis of the cover that helped both of us realize what a cover needs. (Thank you for that!) A lot of the stuff in his analysis doesn't fit the theme and we failed to notice that.
That's why, once the next arc starts (10-15 chapters from now) we'll have a new cover in which we will keep in mind what we want to say with the cover. We've already got a solid idea but Korez needs to practice some specific poses etc.
I hope that one will fit the theme even better. It'll also most likely be the one that will be available on the Amazon Kindle version for Volume 1.
Have a nice rest of the day!
