Alright, I'll be more constructive.
The vibe of the stuff you posted, reads to me as Gen Z aesthetics crossed with a 45-year-old film. It benefits neither. When working with such an IP as ALIEN, one should lean into its (very rich) iconography. Not cross-pollinate it with contemporary (and, to me, lame) design language.
I don't know if you are the designer, for which I apologize for my first blunt response. I can appreciate most creative ambitions. Keep at it.
But it needs to be more inventive. Just a monochromatic screenshot with text plastered on top just doesn't look appealing. It looks busy. Also, to rip that title from the graphic novel and plaster an additional title right on top is just not respectful to the original artist. If you are going to steal, At least do it justice.
Here is an example of the polar opposite side of the spectrum.
Spectacular original artwork that fully utilizes the iconography of the IP. Yet, way overdesigned.
If you were wearing these, it would look like the shirt was wearing you.
Here are my own takes. Feel free to return any criticism.
I try to stay on brand without overdoing it; I create my own assets, And I try to lean into the era from which the subject stems from, like with the 70s ringer tees and stuff.
