The Rebasing of an army

Started to rebase my samurai army. I just kind of like the look when the models are bases on bigger bases. It not onlly makes it easier to move them around but also offer the possibility to make more interesting, dynamic bases. Also it cuts down on models needed.
 I went for 40mmx60mm. Usually this is 6 models but then they have to stand very close. This is fine for napoleon armies organized in close ranks but samurai which fought in a much looser formation I think  the army could be represented in a more interesting way.
