maybe it's me, but rather than grass, that looks like a river. mean, the grass's "ripple" should always go in the same direction, as it follows the wind's direction. then, in the animation we see that the ripple makes a turn to the rigth, instead of following straigth to the left.

althougth this can be easily argued(after all, it's wind, and it doesn't need to follow an strict parttern, and this effect of a 'turn' can be the product of a wind pipe) may it be a suggestio about the `piece. in any case it would affect the final result.

 

what you could check in the other side is what ms Mash potato said about the ripple getting smaller as it reaches the horizont. and i'd like to add that it could be a bit slower too from that depresion in the lower left corner.

 

absolutely looking foward to vote this piece, as this challege lacked animations.
