Completely from scratch actually!

There’s not too many things I’ve done from scratch in Genie Twi although there are certainly others (Ex: Genie Twi’s dress in the Winter Prom). But yes I wanted to make a basic but still recognizable as a Genie bottle. Putting the pixels in just the right shape. Coloring in the bottle in the color of Twi’s coat, making it slightly transparent. Copying and pasting Twi’s cutie mark onto the bottom of it, and then dotting it a bit with the colors in Twilight’s mane and Tail.

I’m also pretty glad you like the design for it ^^
