That jeep is so well done!

This is also in my field, haha.XD I will be working in the automotive industry in the future.

Oh ok! I don't think I ever asked you, but are you studying industrial design? That might explain in part the rocket-jump in your skills. I admit I'm not that good with perspective, props, vehicles and all of that. ^^"

Yes, I studied industrial design for seven years (2019-2026), which exactly coincides with the years I've been drawing this comic. Its influence and help to me have indeed been very significant. For example, the driving scene on this page and the close-up of opening the door at the end can both be considered "product usage diagrams" from industrial design. As for perspective, I use a mathematical approach with the help of perspective rulers and guidelines. I place a figure model nearby to observe the poses from certain angles at the same time. Of course, compared to more skilled artists, my method takes much more time. That is why each page takes so long to complete.
However, one major drawback of the methods is that it tends to be overly "standardized and engineering-oriented", lacking much of the subjective aesthetic quality of art. It can only ensure that the work is technically correct rather than making it more visually appealing. After all, It is art, not mathematics. So I also plan to learn more about this artistic aspect in the future. ^^
I can show you my sketches and some of my process if you're interested in it. I hope it might be helpful to you ^^. I can send you a note with my Discord (if you have it).
