Here is the second still life we worked on. It's an acorn!
This is my first block in:
Here is my finished piece for the 1st pass:

My thought process:
I made the shadow on the right side of the acorn warmer because my lighting was coming from the right side and transitioned it to a cooler bluer shadow on the left. I also tried to reflect the warm shadow on the nut itself and a cooler browns to the cap. I also gave warmer browns to the side of the nut that faced the light and cooler browns to the side that faced away from the light. It's kind of fun to think of temperature but drives me crazy too.
My teacher told me to add more darker values around the curve of the cap where the stem meets the top of the cap to give it more depth. I also need to curve the cap around the acorn more.
