What a pitty you didn't post it as a PNG, now we are comparing 1x JPEG 
compression and 2x JPEG compression.
In the right picture, without zooming I see a loss of detail in the hair, 
its more fuzzy. Around the lampost there seems to be an extra contour and 
the edge of it if softer. Under the lamp in the orange on the wall the 
horizontal lines are more prominent There seems to be more structure in the 
yellow on the wall. The colour fade on the womans back, from the spline to 
the side is less smooth.

There is a JPEG compression utility at:

It has a somewhat different approach, you can specify the visual quality 
instead of the compression rate. Or you can set the desired file size.

price list (and the prices are stunning).
