Can you tell me whether this sketch was hand-drawn or post-processed on paper?

Look at the picture you drew, look at the picture I drew, ah......

I am not engaged in design, I am not a spray, I am just a primary school student who has been engaged in the power tool industry for many years. The picture is good. But you're a layman. There is no improvement in your design, and the changes are optional. Any design that does not take the convenience of workers as the starting point is bullshit.

Very mature, hand-painted is too good-looking 8

I just saw that there is a power tool competition in Puxiang. This should be very good.
