You've got great gesture and movement with your poses and drapery--they both work so well with each other :) I really like the design where the cloak is almost a scarf and he's wearing shorts!
Some good explorations and a nice bold brushstroke. My main concern is that the two characters you're working with look too similar from the silhouette perspective. This can be visually confusing when they're both on the screen. In some of the versions Nafai looks a bit girlish and Luet looks a bit boyish. Luet has the long pony tail and thinner legs, but they both have a cloak about the same shape and other similarities. How can you distinguish them more clearly from each other? The main characters should be distinctive.
