I think you have used the dof extremely well here......getting front edge to center sharp.
Excellent color in that overcast light.....colors are at their truest when it is overcast
Thanks for the critiques. I was very pleased with this image. And I was particularly happy with the background. In provate gardens like this, they tend to frown :( on photographers landscaping the backgrounds so I had to deal with what was there. Shooting at f/3.5 certainly helped. I have several other flowers from Thuya that I like a lot but the backgrounds are a little busier. Oh well. Glad you like this one.
