I tried some pixel art with Bitmap, and it turned out really well. I was planning on making an assortment of colors for the characters, but decided to have red as the main theme instead. I was going for characters that you might find in an RPG game. List of characters [Left to Right] -Mage -Assassin -Ninja -Tank
So basically if you set your canvas to bitmap, set the paint tool size to one, and zoom in a lot you can do pixel art. It will be really tiny though, so you'll have to scale it up with the set size block. Setting the size to 1000 (10x) worked really well for me.
