development process and concept variants

Here are a few concepts that show some development process. It's interesting developing a character from different stages. Sometimes you get a design brief that is extremely open ended, and you spin your wheels developing forever and never seem to hit that elusive target. Other times, the brief may be open ended, but you luckily nail it in the first couple hours, and all the other drawings you did the rest of the week seem completely unnecessary. Then there are times when you get a very specific design brief of an arch-typical character, and you end up honing in on nuance details; ie hair styles, eye configurations, material/texture contrasts, unkempt fur vs slick skin, soft translucent tissue vs crustacean type carapace. Still, these details could heavily change the feel of a character, especially when you are working in a non-fantasy setting. In the end, people don't always see specific differences, but I hope they'll feel the difference.
