Less organized, disheveled, haphazard, shoddy, slapdash, messy, jumbled, cluttered, chaotic, sloppy, untidy, uneven, patchy, ramshackle, slipshod, rumpled, unkempt, ragged, rickety, scruffy. These antonyms describe the opposite of "more thrown together," indicating greater care, attention to detail, and overall coherence.

Conversely, these antonyms embody a sense of intentionality, clarity, and soundness that bring a level of cohesion and order to any endeavor.
