Megashark 4: Megashark vs Colossus

Here's a variety of the design work I did for Megashark vs Colossus - most notably designing the giant Soviet era Robot "Colossus", the "Attack subs" and the "Super yacht".
Design direction for the robot stipulated it be 1970's era Soviet technology, but then ultimately that was mitigated by the fact the distributors simply wanted a robot version of the "Titan" creatures from "Attack on Titan".
For the subs the direction given was that it should look somewhat like "a killer whale", and the Super yacht's design was predicated on all the various things it was required to do within the film.
For the submarines and Super-yacht, I made simple 3D models in Newtek Lightwave and then drew over the top in Adobe Photoshop, which permitted Me to get nice clean curves and shading quickly.
My personal favourite iteration of Colossus is the "Military Green" one swatting a jet from the sky.
Also, as a tribute to Gerry Anderson, one of the sub designs is based on the Russian attack sub from an episode of Joe 90.
Final designs above, development designs below.

CTHULHU, Lord of R'yleh

First attempt at CTHULHU that I am somewhat happy with... I get so bored with the uninspired versions of a man with an octopus for a head and some bat wings stuck on for laughs.
Cthulhu is described as being ...not composed altogether of flesh and blood. They had shape [...] but that shape was not made of matter...
I always recall an interesting demonstration by Carl Sagan on the show Cosmos, where he demonstrated what a two dimensional person would see if a three dimensional person entered their world... This is an extrapolation - what would we see in three dimensions of a creature that existed in four?
As for wings, I went with pterosaur wings, instead of the usual "dragon" wings, since I see Cthulhu using them in a more penguin-like fashion to swim under the ocean, rather than to fly in the air.
At Cthulhu's feet are the vanguard of an army of "Deep Ones", who worship Cthulhu and dominate the deep, now ready to dominate the land.

Shub Niggurath

A quick concept piece of Shub Niggurath, “The Black Goat of the Woods with a Thousand Young” - one of the many creatures and entities created by renowned cosmic horror author H.P. Lovecraft.
She is the "All-Mother and wife of the Not-to-Be-Named-One".
There are no real descriptions of her in the stories, so artist frequently depict her as a big blob of tentacles, occasionally with legs and often with many mouths. Tends to look a bit silly really.
Not sure if this concept is any better but went with the fertility idol aspect of Shub Niggurath, hence the huge udders and pregnant belly.
"Her" mere existence in our world is forcibly tearing the dimensions apart in a fiery conflagration that trails behind "her" as "she" moves.

Would like to add a greater sense of scale and motion and power if I get a chance to revisit this idea some time.
