Well, it's an interesting concept and I love pixelart. I really liked the opening thing about not turning it into a dystopia, but there was neither a city nor a dystopia in this. The line about there always being clear skies after rain, but there never being rain was quite clever. Not just as a play on the saying, but also a signifier as to gets going on in the guy's head. I'm not sure what the angular black object towards the end was supposed to be. The ending showed us the guy was really sad or stressed out or something, but we already knew that. The background was too dimly lit for me to discern anything else and I don't think it gave us any other clues. In the future, try balancing aesthetic with clarity of information a bit better. The dude's walking from the frog's eye view was also a bit wonky because the upper half of his body wasn't turning at all. The animation in general was pretty good, and I liked the way the wind stopped blowing in their hair. It felt pretty impactful. Music was also nice.
Overall an interesting concept, but a couple missed opportunities. Try fully exploring your settings and stories in the future. This was kind of an exposition dump from the character inside the dude's head followed by more exposition that we already knew without any new (or maybe visible) clues. Showing or implying can often be better than simply telling. Like if the thing that happened was someone died or he lost his job, show the tombstone and someone's legs standing over it or him clearing out his office or something. We already knew what the thunderstorms meant. Show us the character looking up instead of telling us explicitly that it's been getting worse and let the thunderstorms signify what they signify. If this was about not suppressing emotions, maybe you could have said or showed something poetic about tidal waves or floods or something. Try experimenting with that and keep it up, you have some very interesting ideas!
