Roman face

When we were in the UK we were lucky enough to visit a small collection of Roman artifacts on a local farm. All the items had been found on the farm which is the site of a Roman villa.
I decided I would stitch a Roman head as a gift to the owner of this farm. After some research in my embroidery history books and some from the library I have come up with this design and started to stitch yesterday. I am not sure the Romans did much embroidery but there are a few examples of pieces using mainly split stitch, will that's what it looks like from the photo.
