I enjoyed this exercise, part of the reason I took this class is because the little mushroom caught my eye, I love them and all the variations they have. I think they are a great subject.
I kinda surprised myself with this exercise and found that the layering techniques were so helpful in creating great dimension.
The fern was a bit more difficult for me. My eyesight is pretty bad and I'm waiting on a new near sighted prescription. I found the fine details in the fern to be a challenge. But I'm pretty happy with the overall result.
