wow, Bernie..this is hot stuff! well, it would hurt to have one of these prick ones fingers!! I do love the macro of these thorns...can you get a big closer yet? and take a picture of only ONE or two of them? this is a lovely photo!!
I like this shot, but I think it's a little out of focus and the leaf on the left distracts from the main focal point. My suggestion would be to try cropping this (if you have a bigger resolution, crop to 1600x1200 so only the thorns are showing =) If you'd like, I could do a quick crop on it and upload itto show you what I mean. Keep shooting =)
