Albert,
Yes, the problem with some of the rotations is that they are sharing a convergence. https://drawabox.com/lesson/1/16/notrotating This isn't a huge problem though and you did well with your rotations for the most part and you seem to have a intuitive sense of 3d space already.
Here is a tools list you can see that you can use for lesson 6 onwards. https://drawabox.com/lesson/6/1/tools The constructions in lesson 6 and 7 can get quite complex and using a fineliner would probably result in too much information on the page at once.
