Here is a quick little custom for MP10 I thought I would share for those wanting to try it. As you can see below, the eyes on MP10 are rather dead looking. They chose a dark blue, and it was one of the weaker design elements of the figure. The Hasbro version went with lighter eyes.
Rather than spraying the eyes, I used these yellow paint pen. I chose yellow for the G1 toy rather than the cartoon model.
And its that easy. Below you can see some photos of the finished product.
