Big cat in a smol box

A picture that took too much time to cook has been born :0. An attempt to design with an idea that began very cheerfully at the stage of a character drawing and descended into production hell on drawing the background. The basis for the picture was a series on Zilla and memories of an excursion to an abandoned Soviet submarine base. It seemed to me a cool idea to place a hand-held kaiju in the dry dock of the base-a tunnel passing under the mountain into a hidden lagoon.

I recently reviewed the film with this overgrown lizard and I must admit that it is looks not that good as I remember it. But its design still gives me more pleasure than its original)
