I cannot agree more with @Ofnuts, depending what you did to this image in GIMP, for example just bringing up more sharpness, will increase the size of a JPG for the same compression ratio.
Just out of the jpg topic, do you mind if it's a webp? Usually webp have a lower size than jpg for the same compression ratio, you might want to try it out (just put the extension .webp instead of .jpg when exporting
