Some constructive criticism.....
The coil looks fine to me, but it's way to high. Get it as close to the air holes as possible, and center it between the two air holes. Keeping the coil close to the air flow will improve flavor and reduce the vape temp.
As for the wicking, the density of the cotton doesn't appear to be enough. It should fit snugly in the coil, with resistance as you pull it through.
What has worked best for me is to keep the tails long, then fold the ends back towards the air holes so that the "elbows" of the wick sit above the liquid channels. The ends of the tails will end up near the air holes. Picture a sideways "U". There should be enough cotton to cover the liquid channel. If the liquid channel is left open to the deck so that liquid has an unobstructed path to the deck, it will flood/leak.
I promise to take a photo next time I re-wick, but this method has worked perfectly for me, with no flooding.
