Alright, more like 65 days, but still :)
Either way, lot's of work has been done during those 65 days.
These represent a selection of concepts I created during my time
with Milk VFX when I worked on the Dinosaurs In The Wild project.
Recipe
I took bunch of my dino models of whom some rendered in 3ds max, some straight from zbrush and couple of them grabbed from Milk VFX turntable videos. All of these models were mangled and puppeted via photoshop into various poses, then slapped onto photobashed environments. Goal was to rapidly produce as many images as I could in as short period possible but to still keep it readable in terms of direction and feeling of what the final piece could come down to.
After we wrapped the conceptualization stage which lasted about 15 days or so, selection was narrowed down to about 25 images that we kept working on and making them into high quality production stills.
