Yes. Once again, I'm inclined to agree with rayw on this.
First and foremost, use names. Unless the character doesn't play a significant role like a butler or a waiter, use names. It confuses everyone when you replace the names with letters. Even saying something like, "Tall German Guy" is better than calling him "C". I know their names don't really matter but for the sake of readability, just use names, even if they're dumb.
Second, you need to be more clear about your descriptions. For instance, your first shot says, "Shot of the sky. The SUN is isolated and waits (sic) paciently, just shining." I had to re-read that sentence twice just to understand what you were talking about, which means its not very fluid. It would have been better to say, "Shot of Afternoon Sun on a clear day." Another example is when you describe B's room. "The ambient of B's living room is dense." I assume you mean that the lighting is ambient and you can see high density and contrast with the shadows. For something like that, all you really should be saying is, "B sits in his ambient living room."
Third, your slug lines are too vague. You say things like Brazil or Germany, but what part? City? Country? Suburbia? You also say things like, "Day" or "Night". Well, what time of the day or night? Early? Late?
Fourth, your transitions are confusing, especially for the beginning shot. I get the sun, but why the dogs running? Where the hell are we in this scene? Which character lives around that scene?
Fifth, your dialogue doesn't sound genuine. No one says things like, "How long are you going to be like this?" when they see their friend flicking a lighter on and off. They would be more like, "You gonna be doin that all night or am I gonna have to drag you to this concert?" That's another thing. Why is his friend even there? What is his friend doing? Just watching him? Why? You need to be mindful of these things.
Sixth, your story sucks. I'm sorry to sound harsh but I'm a believer in honesty when it comes to these things because unless you know the truth, then you'll spend a bunch of time, money, and effort on it, only to come up short. Always invite the truth, even if its something you don't want to hear. Now, why does your story suck?
Obviously no one has the absolute say as to what's good and what isn't. At the end of the day, its all relative, but in my opinion I don't like this movie because its confusing and non-sensical. You need to be clear on the point you're trying to get across. As far as I'm concerned, I'm watching a movie about some people killing themselves in almost the same manner all over the World. That bares no significance or meaning to my life. If you're trying to show random people around the World come up with the same idea about being one with nature by burning yourself, then it needs to be stated more clearly in the dialogue as well as actions. Why these people? What makes THEM so significant?
Above all though, I don't like the message you were trying to get across. I see what you're trying to do, but it sounds like something my fun-loving stoner friends would come up with. If there is one thing you should walk away with from this topic you created its this: The question, "Why", is singlehandedly the most important question to ask in your movie. Because if you don't have a reason for why something is happening, then why have it happen at all? Why even make the movie when there isn't even a why attached to it at all?
So, the only reason you have for making this movie is to show how people yearn to be one with nature by literally burning themselves into it. So then....Why? Why do they want to be one with nature? We see that they want to, which explains what they are doing, but why are they doing it? No doubt, its neat to watch a movie about people burning alive, but unless there is a significance as to why they're burning, then its basically snuff.
I think you need to focus on your why before you do anything. For instance, with the Happening, their why was that it was some sort of phermone the plants were giving off to kill humanity. It was a shitty why, but at least it was a why. You have no why. You just have a what.
