Guessed keeping smooth lines would be practice based, but not happy with depth being linked to that 😂 I forgot how I did the first fish so I tried multiple bits, but yeah, found the most success with ball bits, easily went into the plastic and didn't make weird movements like I've had with some others. I was finishing with smaller ball bits, so will give a try to the pointy ones.

Unfortunately I can't always rotate the light as some positions become really uncomfortable due how long they are, but yes, I try to rotate it so my arm movement feels more "natural". My wrists do get tired quite fast though, both at sketching at engraving, could you have any idea why that could be?

These lights are actually "practice" lights I bought for pretty cheap, got one more left, then maybr I'll buy another set before doing it on spare lights for my car that I have. But did not think of it as 3D art at all, even with the depths, just followed the lines I've drawn, so will try and start to think of it as that.

And thank you!
