Using Gimp to get a better trace in Inkscape

Looking to trace this image in Inkscape there are several colors that could interfere and as it is a JPG even the solid colors are not solid but messed with by the JPG compression, Inkscape trace will try to follow those, but Gimp masking can do a cleaner job.
