Brother, rendering is not very important in original design. Good creativity means that the lines are all fine. Don't tangle. If you look at your own rendering, it's not very brilliant. You should study more practical design.
It is an amateur work three years ago. We mainly do export design such as electromechanical design. Vehicles are only design hobbies, but they are also better than fake designs. Too avant-garde is conceptual design.
It is good to have a hobby.
This rendering is really Buddhist
So old-fashioned, it feels like something from many years ago.
