Ethereal Serenity, me and a cake-sized frosted cat cookie!
To draw this, I used this reference for Ethereal Serenity and this reference for the pose (although pony size was modified). This is the first time I did some shading with color pencils and I'm quite happy with how this turned out!
Big thanks to my friend Arterial for coming up with a mane style for me, I will use this from now on!
