Look at how they shine! And I think whimsical combines with classic with the addition of the soft pearl and 'diamond studded' collar spacer. I have no idea what you actually call that, but it's pretty ... and from every angle. I don't have too many of these, so they only come out when I really love the focal bead.
For the rest of the beads, I prefer to use a mixture of 6.0 and 8.0 seed beads as it adds a bit of texture - but it's not necessary - you could use one or the other. I do recommend though that you create the focal point at the bottom end of the hanger - this will ensure that it hangs below the boughs and draw your eye to what's important - the ornament itself.
