Hello. First I would say it is a really good drawing for a freehand one ! There is indeed a mistake with the verticals (in yellow) => It would be a 3PT perspective if they all converged to the same point. here they don't so we get the feeling that the chair is not upright. The red lines are OK except for the back leg of the table that is too long. The purples lines are less converging => you were maybe more focused on the red perspective ? Hopes that helps.
Ooooh thank you! Those corrections really help me look at it with fresh eyes. So, it seems when freehanding perspective I tend to imitate the exact angle of neighboring orthogonals instead of adding in at least a little bit of convergence! Good to know, will be working on that for sure <3
