Filler makes models.

Lowpoly is totally cool, but is there a particular reason you have (or need) such blurry and small/stretched/compressed textures?
If you're trying to fit a particular texture size limit I'd recommend just going all the way and making your textures custom pixel art, similar to how Kenneth Fejer (http://www.kennethfejer.com/lowpoly.html) and some other lowpoly modelers do it. That way you can keep your textures limited to tiny sizes but also have them still be readable and crisp rather than looking like vague blurry... shapes.

If you're actually trying to replicate the blurriness on purpose that's one thing, but... some things really should stay in the past ahahaha
Not to mention that some games did actually use pixelart textures (Megaman Legends, among others) but hey, your models, your choice.
