This is great, the use of the grating is awesome and you seemed to do a good job of trying to find an exact center, kudos to you for that! My only suggestion would be that the exposure were a little longer so you could get longer light trails at the top to almost mirror that of the straight lines on the bottom, otherwise this is amazing.
me like!

Also, you've gone from NZ to Malaysia? Lol.
