Mirko_ddd No worries man! I am actually a senior UI/UX designer by profession so I thought I would chime in this project that you are building.
You have done an exceptional job yourself. I just had some ideas that would make this app match more in line aesthetically with the existing Nothing apps (Weather, Nothing X). Along with some UX tweaks that would benefit the end user.
I am excited to try your build when it launches.
P.S. - If I could make a suggestion right away. You might wanna look into this section. @Mirko_ddd
Here you have given a well defined square box for the Submission gallery and a proper circle for the updates. But just below that the āVote Now Stage 3ā plus Image on the right side, they give an initial impression of two separate interact-able items. I would suggest give padding to the elements and creating a proper rectangle with borders just like how you did for the square box above. This will communicate more prominently to the end user that this a one proper element.
