Guys, I have had a short brainstorm and developed some bloodline techniques for my character. I'd like some input on them, just to see if it's worth continuing this line of thought.

[hider=Bloodline techniques]
Shiroi kiri no jutsu (E-rank) - White fog technique. This is as close to a ninjutsu as a wielder of white chakra can come. The user lets her chakra pour out of tenketsu (chakra holes) all over her body. Upon contact with air the chakra forms a mist around the ninja. Much like a Nara clansman can control the dimensions of her shadow a wielder of white fog can control the dimensions of her fog. All the way from “almost invisible” to “completely obscuring(like looking through a brick wall)”. The fog itself is simply another genjutsu trigger, and the density of the fog determines the time it will take for it to work. Executing an A-rank genjutsu with a fog that is almost invisible will take a considerable amount of time and is best done from a safe place. 

Shiroi toguchi no jutsu (E-rank) - White door technique. This is an implementation of the white mist technique. The wielder can use her fog to fill an opening such as a doorway and thus use the doorway as a trigger point for genjutsu. Because the target will only be in contact with the fog for a very small amount of time the mist will have to be quite thick and as such clearly visible. This is best used as a trap or to secure a hiding/resting place. The duration of the mist is dependant of the level of the genjutsu bound to it. An A-rank will only last for a few hours while an E- or D-rank might last for weeks.
