I really like the antler in that it has some of the bark on it. I think that little detail makes a world of difference. When antler doesn't have bark on it, it just looks kind of dull to me.
The scalloped pen looks good. The scallops look even. That's harder than it looks. At least it is for me.
I'm just wondering why you didn't complete the assembly. Or am I missing something? (which is entirely possible)
.
I like the pink & black segmented. But I think it would be better with some aluminum separating the segments. But that's just me.
All in all, a really nice group.
EDIT: I forgot to ask, is that last pen one of those sunflower seed blanks? If so, was it prone to chip outs? I've been thinking of getting some of those, but I think I need to turn some of what I have 1st.
