a lot of webtoons use premade assets for a lot of the backgrounds. this helps to keep up with weekly release schedules. a 3d car is easy to find and can be tumbled around easily. but a smashed car would need to be redesigned and hand drawn. and the artist needs to consider whether it's worth it.
Given the importance of that scene, and when considering how the destroyed car would have further impacted the viewers emotions, my personal opinion is that hand drawing that panel would have added to the intensity of the scene. I feel it would have been worth the effort. But that’s just my own personal feelings. It wasn’t a small moment in the plot.
I was once in a car wreck, after falling asleep at the wheel. My pet had died the night before. I had watched him die; likely from heart failure, due to old age. He was suddenly in pain. He suffered for a few moments and then died. I cried the whole night. I was exhausted by morning. But reality doesn’t stop just because you’re tired.
I headed out. Then, about an hour later, my SUV rolled over on the highway, rolled off the highway, rolled into a tree, and broke in half- with me in it…
Even excluding the damage from the tree (the tree hit the side of the car, tearing through the backseat), the SUV’s roof + its windshield were crushed and the glass was shattered- but due to safety glass it was intact- kind of like a shattered phone screen.
Point being- that van in the previous chapter is way too intact. It was side impacted by a massive truck, then flipped up into the air, then dropped on its roof. Where’s the impact damage?
