these robots are like us under the steel;loving and warm,but willing to kill to defend their home and themselves. doing all they could in defending laputa against in evil man bent on the power to live eternally,fallen by his own pride as we are..so..we all relate to one or another character,if not,all of them.
I know this is an old piece of yours, but I'm so glad I found it. I love this movie and am always happy to find artwork on it. As usual, the colors are really nice and I like how you have the background more out of focus, which really helps center the attention on the kids and the robot. And nice job on showing the metallic texture of the robot!
