Low poly research

So it's time to think about the art style to go with the project, considering time and man power limitations I need to be able to whack out the content pretty quickly, so I'm thinking of doing low poly graphics, maybe mobile development level, I'm simply not going to have the time to produce really detailed work if I want to have a playable demo.

Here is some nice work from "Murph" (gardenturtle.blogspot.co.uk/), who is a character artist at Blizzard, this is currently the level of detail they are putting out for world of warcraft, I'm not too sure about the polycount but the texture quality has increased massively, they have some great texture artists at Blizzard.

This is the "look" I'd like to go for, but maybe not as detailed (I'm not skilled enough to paint textures like that either way)
