I personally wouldn’t do a photo with a Beatles t-shirt on. It makes it look more like the work of a fan and less of a professional. I also think it establishes the site too much as a “Beatles music on the harp” site, rather than as a harpist site.
I listened to the recording of Asturias, and I think you really got the feel of that piece and translated it quite well into the harp’s sound. I prefer your interpretation to a recording I have of a very well-known harpist playing it, who I think missed the mark on it.
