here's how i like doing my graphics!
first, we get a reference, and i'm going to use a pokemon i like and is relatively simple to draw:
+ 
vileplume!
so, first i create a new image of 64x64, and make a pallete from the sprite. you don't have to do this, but i like planning out the colors before i start to make it feel more organized and you can always add a color if you forget the light blue like i did
