That's a great cover! I love the simple white design and it gives it the classic Final Fantasy look. One gripe, and I'm sorry, because I'm a grammar nazi: The syntax and some of the punctuation is off. Fixed text version (and please don't be offended, just trying to help!) should be:
The world of Final Fantasy VII is economically, militarily, and politically dominated by the powerful business conglomerate known as Shinra Inc.; a company which profits from the use of generators known as mako reactors. These reactors siphon a green, ethereal energy known as spirit energy or mako energy out of the planet and convert it into a source of power.
You don't need to hyphenate anything and the parenthesis is unneeded. Other words are not needed in quotes because they literally are the concepts, names, and sources of power within the game. Quotes are usually used to denote irony, informal, or improper names. I do find the back description a little too bland. Again, please don't take it personally. If it were me, I'd insert something with a little flair to make the cover look more "official" and professionally made.
Maybe something like:
In a world ruled by the oppressive and all-powerful Shinra Inc., the eco-terrorist group, AVALANCHE, is the only hope for the planet's salvation! Join the enigmatic mercenary Cloud Strife in his quest to aid AVALANCHE in its goal to topple the tyrannical regime of Shinra, end its disastrous use of the life-giving planet energy known as mako, and to protect the world of Gaia from threats from beyond the stars!
Let me know what you think! Again, fantastic cover and it is very well made!
