That is more or less the color you get on stainless. You can experment and get it darker, but you do not need a rotary or expensive Yeti to do that.

The problem with a large image on a round surface is you'll go from perfect focus for annealing(black smooth ) to cutting. That's why you have that brownish mark. Rotary is better for a large image but slower than a CO2 & cermark.
