Easel Image app dont handle intricate designs well when you want the scan to stay true to the source. Using Inkscape to create a black and white SVG is for such tasks much better, also if you want to tidy up the design before saving as SVG

Quick bitmap trace in Inkscape and saved as SVG, then imported to Easel.
No tidiying up of the design have been done.
