I promise I’ll keep this look for years, even if some things might bother me still. Anyways, I tried to keep it more simple this time around.

Extended)
Acidic has the ability to fold her sail up and or down based on mood. The spikes there aren't as sharp as the others. The spikes on her face (not nose) and tail are also capable of movement. The tail spikes can smoothen out and or can take the shape of a spiked tail much like a stegosaurus. The cheek spikes can flatten and or push outwards. These are influenced all based on emotions.
Her mood can brighten or darken the greens on her sail, spikes, mouth, and claws. Acidic doesn't have real acid. Her saliva and claws (only those) cause a burning sensation if it touches an open wound. The brighter the green, the more powerful the burning effect is.
When her colors are brightest, wispy streaks of what appears to be saliva fall from her mouth. It will eventually fade into the air. It is mostly for intimidation than anything else.

Btw, the little dot next to her eye is actually her nostril!

The spirit form will have an alternate bio

(Optional) Acidic's Design History
2017 - 2025

2017
Acidic's first ever concept was her as a shadowy western dragon that was overly agile. She had physical weapons and armor.
There was only 1, maybe 2, drawings of this concept. They were physical, and I no longer have them.

Her western dragon form changed to a Spinosaurus form when a game I liked hosted a Halloween themed art/concept contest.
Said game was dinosaur related hence the change.
Her old name was Acidic Soulless Spinosaurus. The black shadowy trait was removed after this change

2018
Acidic became more and more of a sona
The name was changed to Acidic Spino
Her sail now folded and whatnot
She was both bipedal and quadrupedal
Her nostril took on a more Spinosaurus-like placement.
She gained pupils

2019
Huge redesign
Her name was now Acidic only
She became a full on drake, no spino
Her patterns had grey or black outlines
There were different colored green patterns
The green belly was changed to a black belly
The "acid" could be controlled

2020
Spirit form was now a concept

2022
Redesign
Acidic is fully quadrupedal
There are no more grey/black outlined patterns
The green patterns were darkened to cause less distraction
The belly color became lighter than the primary
Her darkest color was now fully black
The wispy eye trail was only present when she was the brightest
Blood color/red blush was explained
She gained an official spirit form

2024
The primary color was brightened to allow black lineart to be seen better
The darker underbelly is back
Green markings were made more visible while getting a new look
Addition of 3 nose horns
Cheek spikes were completely redesigned
Front paws now have 5 digits
Mouth was redone to keep the spooky while not being overly much
Height was raised to 13ft
Gradual physical changes are now explained via spirit form

2025
Design overall simplified for easier drawing
Nose spikes returned to 2
Previous cheek spikes are back
Light belly is back
Green markings are simplified
Paws are back to 4 digits
Back to 10 feet
I swear I'm keeping this one OFFICIAL
