How can texture play a part of the design?
Perhaps texture becomes part of the concept?

This piece creates an interesting contrast between vibrant color and clean emptiness…

Here we have an interesting sense of perspective —
where are we? What kind of narrative is set up

An interesting analogy to real world objects — there is a sense of
reality and tactility.

Again, very real, yes somehow contrasting with the stark “whiteness.”

This piece is very vibrant and seems “alive.”

Emptiness and isolation come from these pieces — perhaps this could be an angle into “Air” as a subject?

What subject might this relate to?
The colors are playful, but somehow formulaic…
