Post One – I liked it, it was a nice intro, it set the scene really well, and was over all a really nice piece of writing, but you asked for a feedback post, not a praise post, so here it goes.
Language & Sentence Presentation – Your language in this post was nice, it wasn’t overly simple and it wasn’t overly complicated. You did a great job at presenting language that is easy to understand, follow and, over all, read. At the same time, there were a few instances where the words in your sentences weren’t needed. Don’t forget to carefully read over how you write (I know that I slip up on this, so I’m being critical here

). An example of this would be “he rambled on, even as he tore open the stubborn door to his shack and forced its rebellious latch back into place after slamming it shut. He continued to drone on for about two minutes, until he was interrupted by a very, very loud squeak.”
You can change this in a few spots, to make it flow better. I’ll try my best to explain how my train of thought would affect this.
‘His ramblings continued on as he tore open his shack’s stubborn door.’
To me, this flows better, it is easier to read, and will, in my opinion, connect better. The original sentence seemed kind of clunky, and I would opt out for something like this, it connects the two parts of the sentence, relating the door to the shack and explaining his excessive rambling in a more cohesive manner.
‘He then slammed the door shut, forcing it’s rebellious latch back into place.’
Pretty much for the same reasons as the above sentences.
‘His drone continued on for about two minutes before it was interrupted by a loud squeak.’
I removed the very, very, part because the scene already seemed quiet and they seemed sort of unnecessary. Other than that, same as the above examples.
Sorry if this has discouraged you in any way, I don’t mean for that to happen. But your language was good

just try to think about making your sentences a little more fluid, rather than clunky (I know I had/ have this problem)
Post Two – I will read it in the morning and Edit a feedback in afterwards.
