This is a brush i just made which is multi use, it can be used to make bushes, little ribbon patters, smoke clouds, flower petals etc, i hope you like it!
here is a showcase of what the brush can do, note: the smoke next to the brushes shape was done when i went on to the sub tool detail window, i went to brush tip and clicked the little button the right of the angle slider and selected "direction of pen" currently this is set to "direction of line" feel free to change it if you want!
