Looking a lot better now, wood bark usually goes on the first layer as a sort of patchwork, to keep the rain flowing down and off the wood, and then pine boughs and leaves and grasses to soak up that rain. But, either way can work very well. I would advise to maintain your fire a fair ways away from your fuel source and any possible tinder, and to make precautions and add elements to your building that would keep the fire in its container.

Seems good so far, yet I would recommend actually making somewhere to sleep, otherwise its not really a shelter, is it? I would advise you to make a raised cot or bed if you could, it seems like you could segment your shelter in two at the middle, for storage and a sleeping/resting place.

Either way, very nice to see your progress again, keep up the good work!

I keep a large spray bottle with me and I don't go too far from it.
Also, that bark is not the first layer. That is the second layer of bark, underneath the pine-like branches is the first layer of bark. Hasn't gotten wet inside at all, really.
