I’m so sorry I don’t want to be evil...so before I start, this is amazing...so in #1, In my opinion, the flying things in the background don’t really fit. (The exploding mountain is so amazing) In #2, I would add more plants on the ground on the left side. In #3, I cannot find anything wrong with it. It’s so good! In #4, I would add a detail or two in the upper left corner. And lastly, #5 I didn’t really get lol. All these were amazing! Keep it up!
