Looks great to me. Just add some tiny pebbles in the bottom of your wicking cup to help hold the potting mix in. That should do a great job and it looks awesome.
Oh wait, are there any holes in your green wicking cup? I can't see if there are any. If the answer is no then you need to put a lot of holes in the sides and a few in the bottom to allow the water to wick into the potting mix you add to it.
Also, I don't see a side view of the bucket. Did you drill overflow holes in the side of your water reservoir bucket? You don't want that water to reach your upper chamber that holds your mix in it.
