depending on pools and costs, i would have to say % less chakra consumed is not a real helpful tag in the long run.
seeing as how this is the beginning of the game, i really think we should stick to the basics and have 4 BL's that focus around each rank, one for every offense.
as for the description, it sounds good, though it should be [user] instead of [gender], also, i think its OP, and i mean HIGHLY OP to stun and buff yourself all in one go. im not a fan of how TNR did it, and i would like to avoid that as much as possible =x
now, in a RP stand point, i do not see how that is Genjutsu in itself. Genjutsu is all about mind games, if you wanted, you can start it off with the flashing lights, that would initiate the genjutsu, and say something like, you appear to double in size, that would decrease the opponents defenses/gens, but it would make sense through genjutsu from a naruto prospective.
as for the 2nd jutsu:
i see you skipped over jounin, which isnt completely the way to go, remember, this is a new game, reaching SJ should be, and will probably be, a challenge.
also, as for the tags you have on it, i say you are trying to make a pretty OP jutsu. The description doesnt even sound like it would do ANYTHING to sealing opponents BL, nor does it sound like it will increase your damage in any sense, specially not ninjutsu.
as for the description, it should say: blood flowing from "opponents name" corpse. and give it a residual tag.
anyway, thats my input.
