Ok, looks like I'm going to have a little more to say on that submission than on the previous ones
Ch 5 :
Basically, this chapter is exposition about the character's former life. It's good that you kept it short, a longer chapter would have been too much.
"He stroked his goatee with one hand and sighed. " : The apparition of past tense here, while in the flashback, did upset me. Probably it's because I didn't expect to find narrative in a flashback that short, when I'm still thinking about the character in the “present”. Relating the flashback as seen from the “present” would have worked better for me, like : "He had stroked his goatee with one hand and sighed. " I know that structure is a little cumbersome, so maybe it would be better to drop the narrative in those instances altogether.
Maybe presenting the chapter as a single flashback (with a paragraph of introduction maybe) would have worked better for me.
I liked the reprise of "And right is a color of many shades."
Ch 6:
I kept wondering what was the purpose of the "futbol" scene, besides making me cringe (more of that later). It only served to setup that a - there are fireworks around, b - he gets drunk. If you didn't include the scene for other purposes, maybe it would be better to drop the scene altogether and say what you need to say in two sentences before the next scene.
Futbol : if you keep referencing real earth settings and just change the name, but not so much that we can readily recognize the real word behind, you're sort of breaking my suspension of disbelief. Either use a different word to describe something that is similar to something we know, or describe something that is wildly different from the word you're mimicking. If you really want to stick with a word that is that close to a real one, I think "Calcio" would have done the job nicely (and is probably more accurate historically).
Explosions phobia : maybe I didn't pick it up and it was introduced before, but I think you need a little more foreshadowing on that part. As it is, I felt like having the protagonist crumble after hearing simple sounds did drop out of nowhere (even if it's explained).
Now that I found some things to say, it might seem like I didn't like this submission, but I did like it, just not as much as the previous ones.
Still a very good job, keep them coming!
