possible powerfist color change

This is what I have been thinmking about doing to my Imperial Fists in order to get a little more color on them. This was a trial run just to see. THe dry brush didnt come out to smooth and I would spend more time if I do the whole army this way. I likey, what do you think!?

The video is me talking about what Im taking to the conflict gt! Im still unsure!
