Cody,
I've done a few of the goblets... not tried to do a cross on them yet... yours looks fine to me...
On the box, in my opinion which is worth what you're paying for it, I think the lid comes off as an after thought. I think I agree with Charlie W.... a recess in the opening where the lid fits down into and the lines continue over the edge to the lid... maybe a slightly smaller finial. The change in the wood is okay, but think I would rather have seen a continuation of the same wood in the lid.
All that aside, both pieces are attractive and will appeal to a number of folks.
