I tried to make a 4-koma which is a little tedious, but enjoyable nevertheless. Don't know how many of these I'll make but, if a random thought/idea pops in my mind I might make one
but IF the artist was going for a mizuki-style 4koma, he/she might have made the lines a bit more sharper and leave out the small details
then add the light color streaks on the hair as seen on post #3397545 in panel 2 and 3, and make the shape of the chatbox a long-hexagonal shape (something like a hexagonal plant cell) but with the corners smoothened out
