This was supposed to be used for something else but the dimensions became too square-like ^o^;;
:'D I stopped using the airbrush tool because when I switched to the latest version of Gimp, I couldn't get the settings right. Turns out I just had to turn off the hardness x3;;; Now I can use it again!
Yay finally softer shading <333 But ergh it takes longer than paintbrush </3
:'D
