The default look of gimp seems a little unexpected to me. The dark background doesn't match the desktop theme and the icons are quite huge.
The settings allow to make it use the system theme and also inherit icon sizes from there which I found to be a lot more pleasant on the eye.
It seems that the defaults can be configured through /etc/gimp/2.0/gimprc so I wanted to propose to make this configuration part of the Solus package.
