Good job with the sketches - try to scan your work instead of photographing it so that I can see the whole figures - some of them have cut-off feet. Your color final for the characters is good but I feel like the composition could be a little better and the figures could be a little more dynamic. Maybe you could vary their height a little more - taller and skinnier vs. shorter and fatter - right now they are all a little too close. Also - even though everything would lean towards blue, which i like, I would introduce some more hue variations to make it a bit more dynamic. Good.
