Did you enter this? I didn't see it

the one Paul posted is all source (thx Paul), i see some issues, but made another one ill provide the link too. Its quite simple to do but with a tablet even more...well ...dcuplicate layer, "make a hole" (layer mask and/or anything cutting, erasing etc...), darken the underlayer, u can import some source inther too (cloning ,healing,clonstamping) play with burn tool and dodge one (fun part i think but u have to take care of the global lightening/shadowing). U can use bevels a bit but not necessarily....u can use abit of filters like plastic bag or any custom filter to add some viscosity and/or some little hilghts in the crack (but it has to be at a very detail n crisp way). ...

all source (i see some issue again but its better than the previous one i made for PSC i think)

Looking for cool pics with cracks, I'll have to go out and start shooting my own, post any pics that you may have,... anyone?... crack?
