The ones that confuse me are for example 6 & 7, as well as 19 & 20. The boxes themselves are drawn correctly, but it looks as if they are going through each other in a way ( or maybe fused would make more sense). Just give them a bit of space next time you do the exercise.
Regarding the Rotated boxes, you only drew the box in the bottom right corner. Following this example, you should see what I'm implying here.
