Zodiac Flash: A complete KO is not permissible at D-rank, or even C or B, I'd say. Even at A-rank, a simple one-post stun (as in, the target is stunned and unable to take any action, jutsu or otherwise) is very potent. Making someone pass out is an extremely powerful ability, and not to be relegated to lower ranks (even if it's only a chance of success, there's very little way to fairly decide when it works and when it doesn't). This, in its current form, has to be S-rank and nothing else.
Water Reflection is fine, save for that you should state what can break/pass through the water walls (jutsu wise and physical strength wise). Is it inherently necessary that the user activate Zodiac Flash after the opponent is caught by this jutsu? (But, you should wait to adjust this after Zodiac Flash anyhow.) You can put 1.5m in the jutsu's Range: section rather than below the jutsu.
Zodiac Eclipse: So, you hit the chakra points....what does that do besides damaging tendons? Also, you should detail what the damage to the tendons will manifest as. Will it be more difficult to walk? Or...?
The range cannot scale with the rank of user if it's not a multi-rank jutsu; please use one set range and put it in the Range: section.
The Doujutsu itself gives a slightly widened field of vision, which is pretty alright. However, recreating an image of the world behind the clan member by using other senses' input doesn't exactly flow with the clan, due to them not having heightened non-sight senses to begin with. Though I suppose this could scale with the Perception stat, I don't think that it "gels" so to speak with the rest of the clan.
Another notable thing is, in order to use one of your clan jutsu, you would not only need to see chakra, but the Tenketsu themselves (normal chakra sensory cannot do this, to my knowledge); this is something that, in canon, has been exclusively relegated to the Byakugan.....which, with the seeing chakra inside bodies, the attempt to have technical 360-degree vision (by creating it with other senses), and attacking Tenketsu.....this really does look too much like the Hyuuga.
I would ask you to modify your Doujutsu further.
