Thank you. Smoothing is thanks to my lazy man's antialiasing aka using vector ellipses to smooth curves. Did you know that your emotes inspired me to use antialiasing? I started with handmade antialiasing, but recently I have used more vectors for smoothing.
Thanks. Problem is that too much smoothing makes it messy. Bottom one allows more smoothing because it has more space to smooth. I could make lines wider to allow more smoothing, but it would take it further away from official deviantart logo.
