Great colors, great composition. Be careful with how your figure stands...the girl looking into the ice cream truck looks unbalanced. (Maybe if you connected the foot and the ankle? lol)The girl in the front is cropped a bit awkwardly. I would suggest making her a bit larger so you're not cutting her off at her ankle.You can move the truck further back to give more space in the middle ground.overall, fun august!
PS don't forget to make the 8 look more interesting! (especially because you're not writing the month out)
