Pull start on an electric chainsaw wouldn't be useless, if it was used to gradually increase the rotational speed of the motor, instead of doing the INSTANT ON of most electric motors. The lessened instantaneous torque from starting would prevent cumulative damage to the chain links.
I don't care if an artist uses 3D models for something that is to be quickly released, so long as it's not extreme in its difference from the coloring style of the rest of the book. I mean, western comic "professionals" abuse CGI all the time, and no one gets widely criticized for it. Still, it would be nice if they would just use CGI for reference, and redraw it, but I'm not going to sweat over it. Not like any of the comics I did ever garnered more than a couple dozen pairs of eyeballs before I quit drawing.
