Congrats to have finsh the challenge of the death !

Time to start, First of all as a whole your extending lines in the right direction which is appreciate. Secondly At the beginning of your try, your lines was often diverging or was parallel but you corrected that quickly so wonderfull. To continue your hatching line are pretty and your has right on the face which are facing to us. I noticed that you was correctting some of your lines and hatching your lines, don't do that pls try to apply has best as you can the ghosting method and if you fail it's okay however your lines are really nice. Then try to draw more diversify box in their orientation.

That all sadly your try is really good and I don't have a lot to say on it :)
