Both figures look great! Really good blackness, contrast and sharpness.
The question is if the laser follows the contour of the picture, or does it follow the rectangular outline?
Edit: I ask because I can barely see any difference. There are no clear signs of overexposure, like in the very first engraving in this thread. Maybe the contour lines on the right engraving are a tad thinner, but it may also be the camera.
Does the laser change direction at the edge of the figure or at a larger rectangle?
It's not easy to find differences, but there are some small details. I think most of the previous defects made by my mistakes like:
acceleration was too low
my x-axis has one defected bearing and its jamming one fast acceleration(now all gcode are converted to work on y-axis as main moves)
some dirt on a focusable lens and wasn't able to get a very sharp point(now it's better)
Its creating line by line, like a printer. Adding video with an unfocused laser, just for preview:
