I did these in the lead up week to Pacific Rim (after watching it I can't recommend it enough, go see it!). They were all done within about an hour and a half. I even tried some 2d monster sketches in photoshop (I haven't done 2d stuff for literally years!). It was great fun and will do a few more themes like this in future:
Tools used: Zbrush+Photoshop - Wacom Intous 3
Above: This was the first one. Like an evil dinosaur-tortoise head. I tried basing the first 3 kaiju on animals loosely.
Below: This one is kind of a rat-shark. I didn't really know where to go with this one but wanted something with huge teeth! The timelapse and turntable is also below
Above: A bird based one. Wanted to make a beak. This ended up looking like a smaller monster due to the humanoid proportions. The making of is below (minus the beak as they are separate subtools). The video shows more of a dinosaur looking base for the model (kind of looks cooler now I look at it without the beak)
Below: This was the last of the Zbrush sculpts. This was the only one done pretty much directly after watching the movie. I tried going for the smaller eyes closer together and the huge jaw. The parts aren't fully defined and I think the over the nose jaw gives it a bit more comic/cartoony look.
Below are 2 sketches done in photoshop, still under an hour. These were done while going through one of the Stan Winston school courses based on digital to practical design. Explaining very basic and simple techniques just to get some characters roughed out for sculpting in clay.
You can check the full course here. I can't recommend those courses enough
I hope these are enough to get others doing some monster drawing/sculpting, go watch Pacific Rim if you haven't already! Next post I'll review some of the books I got in a recent art book haul!
