These drawings are various takes on the gaint castle needed for the story. At first the idea was to incorporate cathedral architectual elements into the castle design, then the story changed and the castle was carved to be from giant vines that where hard like stone. Finally, it changed again to floating islands and docks for the flying airships.
Here are some older sketches I did at work for a video game project that my company was involved with. The characters are based on initial designs by Brian Wong, but I tweaked the look and colours. The other designs are for an airship that the kids where supposed to travel on.
Here are some character designs done for my studio. The first bunch are rough pencil sketches, and I took what I thought where the best two and inked and coloured them.
