I quite like your day-n-night renders, Carolyn. Very realistic in my opinion. I can see where silent is coming from too with the night scene being a touch dark. But overall a small critique.
Your effort to add grime to the toy truck is a solid effort! Especially on the yellow and blue parts. The [overly] dark crevices on the wheels and bucket could be significantly reduced – like 20% of its current value. But the idea is right on track! Good work.
Overall an A this week from me 👍
