Heat Vision - C rank
Machine Gun Fireball - the amounts are much to large, lower them considerably. Also state specifically for each rank, not just C and S. Table format would be the best way to go
Rain Hell - Again, much to large in quantity, lower, and state specifically duration and area covered per rank. A table format would be easiest for you
Insane heat up - Disapproved all around. you would in turn boil the water with in your own body killing yourself.
Blinding Light - to vast of an area and should not be able to activate instantly on the verge of death. For this to be approved it would have to be about an A rank jutsu.
Return to earth - sounds like an automatic escape from genjtutsu
Burning STAKE - sounds like a more advanced B rank genjutsu
(you are supposed to train the jutsu after they get approved)
Make these changes please.
