I could excpect such post from a noob with less then 5 post here - it would be still funny though, but not from you Oscar - 1. you are a quite experienced modder, 2. you know how hard it's to make a new mod - you have so much dificulties with you first mod - Narnia TW - you have only few own unit models (i don't count Laca's and Warspite's Numidians) and you want to start a new one - even harder to mod.
As for the "how to make less detailed models" (and most of you questions) - simply use search option on TWC (a tip best is Professor420's Video Modelling Tutorial Part 7 - but watch all parts of the tutorial - Prof did a great job).
