I'd like to start off by saying you had one of the more interesting entries into the Patterns Challenge. It definitely reminds me of some of some sci-fi television space shots. Using the Portabello just made it more interesting.
Your focus is dead on sharp. Your lighting adds lots of interest and composition is unique to the type of shot I see you are mimmicking.
I'd really like to see your comments on how you produced the image and what you have done in post-processing etc.
My only negative comment about your shot is that it seems a bit over-sharpened.
Anyway, keep up the good work. You're hanging around in the 6's a ribbon can't be too far off!
VERY imaginative! You've done a great job showing the texture of this mushroom with your lighting. I like also how you've diagonally positioned the mushroom and directed the light so it looks like the sun IS the source of light.
WOW - Good choice of patern and a lovely photo. I love contrast - you definatly have good contrast - would love to know how you did this one. Great work.
