Sooooooooooooooo, another idea I thought of! If anyone does abstract stuffs and is a digital artist as well, check this out. I thought, hey why not have some colors in a shape; whether it be a circle, square, triangle, rectangle, whatever. After that, start erasing parts of that shape until you make a thing you like. However, no adding more to it or undoing anything so it feels like an actual sculpture. Just a stupid idea I came up with.
