To start, congratulations! There is a reason why the 250 Box Challenge is referred to as 'The Crucible', so give yourself a pat on the back for making it this far!
Now, though I mostly agree with the critique above by Gyanyu, I want to add a few things,
I see your most of your lines are very good and show confidence in execution, though, your hatching process could use a bit of practice (as mentioned by the reply above, hatching should be executed just like any other line, e.g. with planning, ghosting, etc.).
Your start was pretty rough, (parallel lines, diverging lines, messy linework, etc.) but you quickly got the hang of it and your technical skills seemed to improve considerably.
Now, whilst most of your boxes feel relatively solid, I observe that most of your issues (regarding convergence) seem to arise when dealing with the back corner of your boxes. This is a very common thing, so don't be discouraged. This is a problem that is quite insidious, in that it worsens with small inaccuracies made prior--and so, remediating this may not be as straight-forward as other things.
The best thing you can do to resolve this issue, (whilst it may sound redundant) is to focus on the accuracy of all the lines you draw. I believe that Uncomfortable puts this best, and as mentioned on the '250 Box Challenge' page, "The back corner is a distraction - a symptom of the individual sets of lines not converging consistently."
As your draw your box, the small mistakes you make in the convergence of your lines slowly build up, and as you continue to go about drawing your box, the mistakes that you have already made will begin to fall on the lines that you have yet to make--and, as the back corner tends to always be drawn last, it always appears to be the glaring inaccuracy most see first.
This is a tricky thing to master, and whilst you have improved considerably, I believe it would benefit you to practice a bit more, employing a more careful/methodical & holistic approach to (all of) your convergences, just to get a feel for it and hopefully see a marginal improvement.
Next Steps:
- 15 Boxes (Hatching optional)
Try to keep focus on the accuracy of all your box's convergences, and you may feel that the placement of the back corner comes more easily/intuitively
