I think the only thing you are off on is the color (which seems to be a tad yellow), but I'm not a photog so hopefully someone else can explain how to improve on this.
thks 4 the compliments.
the 1st pic is a Pink Hyacinth Birdsnest. it was originally a 1.5 inch frag from house of fish.
they r all taken with manual setting/ no flash.
That harley looks like a male...the females have "coloring" underneath....but from the looks of the picture, it might be a super hero. Nice action shot
