Concept Artist for online game

We are looking to hire concept artists who are Asimov and Clarke fans and preferably gamers for an online game idea that we are currently working on. The game idea is based on a futuristic post-apocalyptic world and we are looking to hire artists for the initial character sketches and environment scenarios. Characters that we are looking to develop: 1. Evolved human species that has been living on other planets for over 5 centuries. Their bodies and minds have evolved to their new habitat. 2. Mutated roaches and snakes, who have gained some awesome powers during a radiation attack on earth. Environment Scenarios: 1. A far off planet with futuristic buildings and life forms 2. Shambled but not completely destroyed earth with structures and buildings from the year 2715 More project details will be shared with the shortlisted artists. Please share your portfolios to include similar or relevant artwork and do write about the first images and thoughts that come to your head after reading the above descriptions. We will know if you haven't thought about it and randomly applied. :-) Thanks!
