Alright so this is NOT the original! I learned this from someone else... I just don't remember who! If you DO find the OG owner please attach a anim to them!

Steps to make a galaxy; step 1: Make sure you got all the colors! step 2: Use the paintroller tool and default gray to create the blue-ish color. step 3: while ur still using the paintroller, maybe sure to add the pinkish color by using the grayish (light) red step 4: Use the pen/pencil to make mini dots (those will be the stars) and then use the paint roller for the ††† type of stars!! Thats it! You got ur galaxy! Try to follow these steps and send me the anim where you made ur own galaxy!
