In 1993 Kenner released the coolest toy ever, the Red Rex as part of the merchandise for Jurassic Park, so I decided to do my version of it.
After some research on the soft tissue I outlined the silhouette of the T. rex based on the skull.
Designed the color scheme based on the toy.
I added some textures on overlay mode.
Then created the shadows layer on multiply mode.
This is how it looks with all the layers visible so far.
The "light layer" is a flattened image of all the layers with the brightness bumped up and then some paint over work for the final details.
