Could you test again with -qmin 1 -qscale 1 ?  

I tested again with those settings, and the result is better, but still not as good as a conversion by OS X Preview.  I’m only observing visually, using Preview.app.  The blockiness is especially noticeable on the black shirt chest area.  Here are example files. The one created by FFmpeg with qmin 1 is 609KB.  The one created by Preview is 1.9MB, and is nearly identical to the TIFF.
