I’m not a comic guy so I’m unreliable, but there are moments that to me felt reminiscent of that artstyle (there’s a few style changes throughout). I think the artstyle in general is trying to emulate that sort of rough sketchy artstyle the comics had but giving it that colourful makeover that people mostly know the turtles for from the cartoons. A nice middle ground that makes itself look rather unique in its execution.
The standard design of the turtles themselves feels like a unique take on them, trying to make them actually look and feel like teenaged turtles. I think it works really well.
