Let's rock this party.
Firstly, you should give more insight into your changes. "I felt like it" or "I think this would work better" really won't cut it when it breaks down the math behind all our current changes. How will this effect his attack specifically? (In regards to Scizor.) Who won't he be able to OHKO now? What will the improved defense save him from? How will the decreased Sp. Def allow for a 'chink' when rarely anyone hits him on the special side outside of a fire move?
Posting damage calculations from a damange calculator would really be an improvement. This is the one I use.

Kingdra - You lowered all his stats. That is a bad idea all on its own. Most Pokemon are not consider OU just because of their stats, but because of their movepool and typing as well. (OU is actually all about usage, but that is neither here nor there.) I honestly think that Kingdra is mostly fine where he is. Probably a few points out of his attacking stats. (6-8 from both stats) followed by a measly couple from speed would be more than enough to drop him down a notch. Seeing as his speed (In the rain) and his overpowering STABS (Draco Meteor) are what really make him powerful.
Scizor - His attack stat is fine. A few points from it would be the minimal to take. Honestly, in competitive play, Scizor is OU for one reason alone: Bullet Punch. The access to STAB'd, technician'd priority is what makes him. Without Bullet Punch, he would fall in usage rapidly. Even then, it's not as powerful as you would like to think. It's mostly due to the fact that Steel isn't resisted by some of the most common sweepers and that Scizor can take a hit in return.
If you want some proof of this, look no further than our favorite rat, Raticate: Scizor's Bullet Punch has a small chance to not even OHKO him with Choice Band and 252 Attack EV's. That's not as powerful as many would lead you to believe.
But, in the end, we work as a team. It's definitely give or take. So, you can work with what I said, or try something else. Either way, I'd like to see more of your ideas. (Either here, through PM, or on IRC) That way Pidgey, Gammal, and I could better evaluate it. If you have any previous experience with competitive battling, that is a major plus as well.
