really love the style you're going with, this is literally a page out of my life.
the only improvment i can recomend is going into alil more detail with the iconic emotions. like in the last image, the girl could have more of a blank cold stare, or in the 3rd image, the dude could have more detail such as eyes closer to the edge of his face.
but i love what you've done and only got minor improvment tips. i know that you didnt care about the background, which matches the rest of the artstyle. you knew what you were doing, and that alone is worth alot
