imo pen tool doesnt work with this, actually i think every pen tool effect like that looks kinda stupid. it just looks way to planned out to be anything like your trying to give off. a bit blanned could use some lighter fx, kinda oatmeal like. coloring and lighting is a little off too. i kinda like how the splatters look but could use some blurring to focus more on the focal.
one of your best for sure but still some kinks
