Looks like a good amount of cotton inside the coils, could possibly even use a little more if the hits feel a little light. I'm not a fan of long legs on my wicks though, I usually keep mine just long enough to touch the bottom of the juice well. I have no scientific backup for this but long tails just seem like a waste to me, you end up tossing long juice soaked wicks away. I think of the wicks kind of like a trough:
\__||||__/ short wick
\__________||||__________/ long wick
Put 10 drops in that short wick and it's all going to the coil(||||), put 10 drops in the long wick and it will spread out along the entire wick. The drawback to a short wick is you have to be conscious of it, over drip and you have to tilt your vape so the coils aren't flooded, and if you have juice in your well and your air holes point down, it will leak.
