The main problem you seem to have is having lines from different sides go to the same place (Top lines and bottom lines converge slightly differently). I suggest you try visualizing the convergence point further away from the box. Pay more attention to how the other lines are drawn and what direction they point in. Don't make lines converge sooner than they should. I'm sorry I can't give more advice but I only recently did the 250 myself.

Move on to lesson 2.
