Ballerina

There is a new embroidery pattern packet in my Etsy shop!  The title is Ballerina.  I stitched this from the packet:

On this particular pattern, there are fench knots embellishing the curvy lines.  You may have noticed that instead of french knots, I sewed on sequins!  I have a question for anyone that has experience sewing on sequins - which way should the sequin sit on the fabric - convex or concave?  I did mine convex because I like the way it looks, but I was wondering if there is any advantage  / disadvantage either way? I sewed these on with a bead on top of each sequin:

I have also stitched a few ballerinas:

I will be sharing some more about how I used these sequins and beads in another post - as well as many more of my projects from this pattern packet!  Here is what the pattern packet looks like:
