morrocan design

So my blackwork piece for the RSN is a series of arches from a Morrocan mosque. And in the picture you can kind of tell the floor is a mosaic. So I looked through 3 or 4 books of blackwork patterns, but none of them exactly screamed Morrocan mosaic to me. So I googled up some images of Morrocan mosaics, and came up with this design. The downside is it’s huge. The upside is it’s vaguely reminiscent of the mosaics I looked at. I’m not sure what I’m asking, I guess I’m just looking for feed back before I go to my teacher and try to sell her on using my own pattern in the piece. Any advice/comments?
