Copying the kind of modelling achieved by serious mosaicists is going to require a more subtle colour palette. I’m trying various oxide additives to a pale clay body to extend the range, but no idea how that will come out. At the moment they look like undifferentiated mud pies.
It is also going to require a lot LOT more tesserae, and in smaller sizes to refine the images we can achieve. I made the first few hundred teeny ones. I think we might need a few thousand for the project we have in mind.
Sigh. One good thing: they don’t have to be perfectly made, as it is useful to have a rhombus here or trapezoid there to help one get around the curves and corners. And triangles of course.
Examples to study. I think the pieces on the ideas wall will keep me in my place.
Second attempt (not enough tesserae to complete layout). Highly imitative.
