Sometimes you have to fudge what would look good in real life so that it fits within the style of the game. If it doesn't fit the style, then it's best to adjust it so it does or remove it altogether. A case could be made for either option, but I think they look okay adjusted like that to better fit the style.
A lot of the time when I see shadows in RPG Maker games they're so obnoxiously in your face that it's hard to see the details around them. In comparison, this style's a lot better, though I'd lighten the screen tint a little, personally. It's a little too yellow for me. That's personal preference, though. XD
(Also, hid that image for you, sail - it was pretty huge. Next time remember we have hide tags for bigger images~ ^.^ )
