I was going to comment that both look very much like what you'd find in an advanced beginner's deviantart portfolio...like, late high school-ish age, I woudl guess.

The second is more 'advanced' to me than the first, possessing an actual style, but neither is anything I would consider high quality enough to serve as a project/company/site/personal logo.

Looks like a good start for a Space Force squadron emblem https://usafpatches.com/product-category/us-space-force-patc...
