This week, we all got some feedback from our 2D supervisor Nick. And for my shots, he thinks I should try to bring more spark integration to the highlight parts in the image, such as metal reflection points.
So I use the Luma Key node to key out the highlight parts, and then use the Color Correct node to add the brightness.
I will use Shot 2 to explant my way.
Lighting Shot 4
The other things I did was helping my teammate Nick to do the 3D Lighting / Look Dev for shot 4.
I did it in Maya, and render with Arnold. Here is my render elements.
