Unfortunately you've listed the main resources I'm familiar with, though I have heard people on the discord server talk about Brent Eviston's skillshare courses with a lot of positive things to say. I haven't looked into it myself though.
Now, I am actually going to be cancelling this submission and refunding the credits you spent on it. Reason being, it is not complete. It is one thing to have issues with applying the concepts covered in the lesson - that's normal, and that's the kind of thing we identify in the critique, and send off for revisions if they're necessary. But throughout your vehicle constructions, you regularly stopped way too early, and only explored the most general forms present. For the cases where you pushed things a little farther, it was usually by skipping important steps and not subdividing your construction enough to help position particular forms in a specific manner.
While I don't expect your drawings to match those from the demonstrations, I do expect to see a clear effort being made to actually break your construction down to that level, and to put the time in required to do this for each of the vehicle constructions. For context, that drawing took me several hours. I expect each of yours to take even longer.
Your drawing isn't finished when the drawing session or the day is over. A single drawing can certainly span over several days - however long you need to execute it to the best of your current ability. So stopping at some arbitrary point with basic construction only is not adequate for this lesson.
If you're interested in seeing how other students completed this lesson, you can see their work here (it's filtered down to just show those who submitted for official critique). I especially recommend taking a look at LordNed's submission - his last two cars really show just how far the principles of this lesson can be pushed.
So, as I said - I'm refunding the two credits you spent here, so when you have properly completed all of your vehicle constructions, you can submit again. I will however say that your jetski was fairly well done. Didn't dive into too much detail, but you've captured all of the important forms, far moreso than you did with your other vehicles.
