I know this technique has been done a million times before, but I just like the patterns and textures here. Your thoughts or guideance are always appreciated.
Perfectly places splash of color on this, Dave. This is very nice as is but my only suggestion would be to continue to play with the levels a bit and see if you can't get more separation between the gray shades. Try making the lights a little lighter and the darks a bit darker - might try some selective burning and dodging. That will only add even more interest to an already interesting image.
Thanks once again to everyone for the guideance. I still can't get over the amount of help shown on this site. I feel there is nowhere else that I have been helped and learned as much as I have here. Don't mean to sound gushy, but I truly appreciate the sharing here.
