Not often done.  Looks good!

You captured the random texture of till.  But till wouldn't stay very stable as a vertical cut.  It would rapidly slump.  (My area is mostly till, particularly the drumlin hills that formed from glacial features.  Road cuts through those have a slope to prevent that.  Our house is built on small hill of till, that's why it drains so well giving me a nice dry basement.  But it's kinda hard to grow stuff here without adding a lot of humus to restore the nutrients that leached out through the till.)

It has a good Bay of Fundy look (though it's been a decade since I was in Moncton, let alone on the shore).

Here in the Great Marsh (North of Cape Ann, MA), the muck is very fine and dark gray with a hint of green in full sun. The marsh creek beds are more like native soil inland, with sand, gravel and cobbles

If I only knew back then more about glacial til. The mistake I made was not looking at the big picture.

I used images like this, as a reference.

I will have to look up images of the Great Marsh in your neck of the woods on the net.
