Forget the very ropey sketching, just look at that terracotta colour. Wow!!

The sketch is honestly only barely average but I absolutely nailed the colour of the cut rock sides of the Selby bypass. The sun was bright and made the sandstone cutting glow - it took the edge off of the cold wind, from within.

Geologically, it signifies something to do with deserts and/or iron compounds, I think. I'm a keen but very limited geologist so your homework is to find out if there's any truth in that statement. Then again, who cares? Just look at that colour...
