For OP:
What's your first impression?
It strikes me as a magical fantasy/adventure with a romance (?) implied aspect!
What do you like about the book cover?
The color palette is inviting and nice, it definitely looks great and the character design (as far as I can tell as someone who hasn't drawn before) are pretty good.
What advice and suggestions you have for the book cover?
None; I think it's well done enough to fit in with other trending stories.
What do you think is the genre of the story based on the book cover?
It still strikes me as a fantasy/adventure with that romance aspect.
Did the book cover make you want to read the story?
It definitely does!
For Dialusion:
What's your first impression?
It strikes me as an action-themed story (it brings up a lot of Yugioh/similar summoning show themes to mind.
What do you like about the book cover?
I think it does a great job of showing what to expect in concerns to the story; the split panels for each character (hieroglyphs and monster), the little devices on their arm, and their expression really sell that it's going to be exciting and action-packed.
What advice and suggestions you have for the book cover?
None; it's very well done!
What do you think is the genre of the story based on the book cover?
I think it's action/fantasy, potentially with a fantasy aspect based on the more magical (?) details.
Did the book cover make you want to read the story?
Personally, I'm not one for very action-based stories, but I recognize it would definitely be popular with another crowd.
