The JAL pics in the first post are better (both not overexposed, the whites still have texture) but still jaggy in places.
For all shots: reduce the saturation to more 'real' levels. They all have a neon-like look.
I see this more and more in screening, the cranking of the saturation. Be careful with that. Besides looking unnatural, it creates nasty side-effects deteriorating the overall quality (losing detail, grain, 'running' colours, etc.).
