7 In 1 Prime Model Scriber with 7 Blades Gundam Resin Carved Scribe Line Cutting Tool Chisel (0.1/0.2/0.4/0.6/0.8/1.0/2.0mm) Red

I'm using this chisel set with the .4 and the tape it came with. Basically just scribing each line individually starting with very light passes (basically the weight of the tool) and getting progressively more firm. I think I'm having a hard time doing one fluid motion which I think is where the scraggly look is coming from. Trying to figure out if there's anything glaringly wrong with my technique before I form bad habits.
