My idea is another Azula pic.

She's seen from an areal view while pinned to the floor as someone services themselves using her generous bust. https://hitomi.la/reader/50316.html#4

Pose wise, she is laying on her back as someone rubs their duck between her boobs while she brandishes an outraged expression.

No background, unless you count the flooring.

Expression: Like it says in the pose her facial modus, can you make it a mix between this https://xy-06-w.mangapark.net/a1/81/5c5e2eeda1ecd1086974181a/22_214034_1066_1600.webp and this http://pictures.hentai-foundry.com/c/CaptainJerkpants/550767/CaptainJerkpants-550767-Patreon_Your_funeral....jpg

The attire's the same as with previous commissions, flower like outfit. Only parts of it that're visible are the brazier and shoulder straps as with the https://hitomi.la/reader/50316.html#4

As far as fine details go; mmmmm, you think you can add an extra scene beside it where a tight closeup shot of Azula's lower mouth appears to be licking her lips? Something like this: https://www.dropbox.com/s/xvnwoaa0fy2ro0b/26_263270_835_1200.jpg?dl=0
