Welp, you asked for critiques, so I'll give you my positive thoughts and my negative. Just remember that just cause there are bad things, doesn't mean that what you wrote is bad ^_^ Also, because I have too much time on my hands, I'm going to do it as a point form PMI chart.
-I really like your word choice in a lot of places. You use descriptive words, but it doesn't sound like you're just trying to sound intelligent.
-Your rhymes are pretty solid. You have a lot of clever rhymes, and you know when you don't necessarily need a perfect rhyme.
-Your poems are all interesting. They all keep the reader engaged.
-All of them sound different. It doesn't just sound like one really big poem.
-You need to think about the connotation of words. Poems are about saying as much as you can, without necessarily writing that much.
-Keep a steady mood. For instance, in the first one, "The teenagers scream at parents as if they did not matter" Line is pretty strong, but then "Couples spat as if they're uncooked pancake batter." That's a whole different mood. It might be better if you had words that felt the same as like snakes, and scream, and didn't matter.
-Think about your beats in your head. I know poems aren't songs, but generally they flow a lot better if you have the same (or almost the same) number of syllables. say each couplet out loud, and if it sounds like it flows, you know you're on the right track.
-I know that you're going through some stuff right now, but even so, if you're looking to improve, it's not a bad idea at all to try to write poems about everything. Even if you're not happy, trying to tap into that emotion and write something joyful and upbeat while you're upset is a great writing challenge.
-You know lots of really fun words. Vocabulary is a poets best friend ^_^
So yeah. There's my 2 cents. Overall, I quite liked it, and I would enjoy reading more things that you write
