Results: The AI closely follows the painted mask for composition.

The refinement process:

Initial mask gets you 80% there
Fine-tune mask based on first results
Add artist style strings and LoRAs
Multiple generations + mask adjustments + detail tweaks

Final outcome: After several iterations, you achieve the exact diagonal composition you wanted.

Key insight: Manual masking isn't "draw once and done." It's an iterative process - generate, see how the AI interprets your mask, adjust, repeat. The mask gives you compositional control that's impossible with tags alone, but expect to refine it based on what the AI produces.

This is why manual masking is powerful but time-consuming - you're essentially negotiating with the AI through visual boundaries until you both agree on the composition.
