can u add a bumpmap for gimp i dont have photoshop?
It's even easier with gimp
here is a tuto for bump map effect

you just have to choose bump map rather than emboss, donc choose very high value to keep it natural
if the effect is not good enough for you, make a copy of the original image, remove the color information from the copy, turn it in negative then use the emboss effect(not bump map) and then encrust it in the original image
