Why did not it exist? Simply because Synthwave was born Adult, after all it is a synthetic that was produced by a corporation.
But if there is such a version of it, I imagine something like this.
Cute and adorable, innocent.
AND THE MOST IMPORTANT
While I was doing the drawing shading, I tried to do as usual my normal style of hair, when I made an accident, a scratch on the hair that went out of line, before I erased it I noticed something “wait … this can work” so I started to play with the lines and make lines in the mane, and accidentally I ended up developing this style of doing mane xD
So when I finished the drawing I thought, “How come I never thought of doing this before?”
