Perhaps ya just need a little time to see the differences. I was already shodan in shotokan when I was introduced to mande muda and the forms therein. I think you're working on the "monjet" form...anyway, I think the biggest difference is in what I call the "compass".
In Japanese arts like karate and kobudo, we are taught all about the eight directions of attack. You are positioned in the center of a giant compass with these 8 directions from which you may be attacked, and you train to defend those angles and retailiate. In shotokan especially, we attack very much on a linear plane until a more advanced level of understanding...like your "Mack truck" analogy from another post.
In tjimande we are taught that your opponent is the center of the compass, and you move around him. There's even stepping patterns we are taught to use to gain advantage on angular attacking. So the focus becomes more of an effort in agility, but with practice becomes natural.
