For one, setting the maximum carve width as something less than the maximum dimensions of the drawing, and then allowing the depth to remain automatic is going to do some weird things, particularly if you’re using different widths everywhere.
I would suggest that you set a maximum carve depth as something reasonable for your tooling. 1 or 2mm given that you have the tool defined as 1mm/pass will give much more reasonable carve times. You can then set a reasonable line width to either give a carve of the complete figure, which would be to set the maximum width as something that will allow the entirely of the piece to be carved.
As is, it looks like Estlcam is getting confused generating the gcode. If I enlarge the .dxf, I get some gaps and oddities in the drawing, so I’m guessing that some of the problems are related to that. The shapes aren’t properly closed, and that will definitely result in some weirdness. I’d say that it looks like you generated the .dxf file from the .jpg file. Perhaps something didn’t translate quite right. I tried some bitmap tracing in Inkscape, and got some varying results, with some wobbly lines sometimes. Jpeg is a compressed format, so it does sometimes have some weirdness in it that doesn’t really show up to the eye.
If I were looking to do this as an inlay, for example, I would probably choose a large value for maximum carve width and a small value for maximum carve depth. I’d probably also import the .dxf into a CAD program and resolve it to a fully closed and constrained sketch.
