Hi .
I actually use inks for free hand detail, and I usually mix them with an equal quantity of paint for the following reason. The inks I\'ve got are the original citadel expert paint set inks,(yeah, they\'ve lasted this long.) that came in bottles that look like mini vallejos, these inks have the annoying property of drying with a gloss if you use them undiluted, hence I mix em.
I normally use a glaze to tie together the highlights and shadows, as Erik(El maestro, I tip my hat to you sir) said, it normally works for me but some times I\'ve over done it and taken all the contrast out. it\'s kind o do or die, especially after you\'ve spent alot of time blending
