I can see that you have applied the guides nicely, and it's expected to make mistakes during it. In any case, the revisions you sent show that you have acquired the understanding of the concepts and have developed better skills in estimating proportions, some of your cylinders in boxes being really nice. You'll definitely have more time to practice them during the later lessons and warmups, of course. But, for now, I don't see any reason to hold you back any longer from going into L6. I wish you the best of luck there, as these last lessons will truly put your skills to the test :)
