I had difficulty thinking about what I should add to the video. Then I went with the flow and added one effect following which things just started unfolding.
First, I added the snake texture to the face, I had some problems with the texture because it was stretching when the character was moving. I fixed it by roto keying the texture. For the texture, I didn’t add a frame hole. One more problem that I faced was that when the face was moving, underneath the texture, light would pass through it and I didn’t quite know how to fix it.
Next, I moved on to tattoos and Jacket patches. These were fairly easy. While merging with the main plate I used the operation stencil and this helped and the light didn’t go behind the tattoos. The only downside is that the image becomes black.
