Good finish. Added a back drop (based on a prior comment) to at least give some sort of color out there. The reflections ended up pretty well.
I did notice that the shadows, and reflections, were a bit odd in some spots. For instance the pin to the left of the bowling ball. There’s some sort of pixelated bit on the front. I’m guessing this is from the three light setup I have and how bright it is or its position. Is that the case?
