Great Photos. I'm using your main page image right now on my desk-top and it looks great, really great there. You have nailed the focus, color and composition and as a fellow photographer, I'm really happy to see these close-ups.
PS... Welcome to the forums, you have found a wonderful (forgive my bias) place to share and learn from. I really hope you love it here and you truly made a great first impression!!!!
