Those are some nice straight lines there!!

In the first week it seems like your line converged a little too soon, you seemed to correct that and spread them in the next weeks. By the 50th day or so you pretty much got it!!

There seem times where your lines tend to get close a little soon but all in all they all seem to be nice cuboid figures :)

Just watch out for those convergences and always commit to the line. One or two of those cubes seemed to have lines where you corrected course halfway.

I like how you spotted flaws in your work and corrected it.
