Hi Envar...
Plastic Bottle took the words right out of my mouth...the red flag just adds that bit of dynamic colour. Remember Spielberg's little girl in the red coat in Schindler's List.
The red flag just adds that artistic touch and makes the whole piece special.
Whether it needs frosting, I'll leave to more experienced eyes. But it might have only been put in place as a recognition emblem just before the charge.
I do like it against the forest background best of all.
I go with red!
Wonderful
Peter
