To all who might have downloaded this file:

i noticed that DeviantArt, where this file resides, does not accept .tif images and automatically converts them to highly compressed .jpg files.

a 16 bits file was not warranted here, so i changed it to 8 bits;
and i also converted the original file to .jpg in Ps, with minimum compression.
the file is now about twice as large as before.

if there is anything i could do to improve it further, please tell me.
