Shot with an old manual focus Vivitar 90mm F2.5 macro lens on the D90.
I used the onboard flash, it was just too dark for shooting hand held otherwise.
Interesting comp that looks great considering the use of on-board flash. The white look pretty good on my monitor. The black background sets it off well. Nice.
I love the plant - would love to see you eliminate a little more of the tree branch and really get in on the fungi.
I cleaned up the URC and cloned the branch at the bottom so it went straight off the frame. I selected the BG and took it to all black as there was a bit of posterization going on at the bottom (probably from the upload.) I then added just a hint of kick with a slight levels adjustment. See what you think...
