One decision you need to make:
To base or not to base, that is the question.
Obviously, the mini's look cool when based (and by basing I mean putting grass, rocks, etc on the base like Ras did above.)
However there are two advantages to non-based miniatures.
1. Minor Point. They can be used in any terrain with minimum distraction. You put grass-based minis on a snow-field or stone tilemap, they look worse than just black bases.
2. Major Point. If used for gaming, eventually, the basing does come off and it also prevents you from putting any of those sticky notation thingies on the base. The gum the sticky stuff uses will usually strip the basing right off.
One thing I've noticed, YMMV, fur comes out awesome if you use two lighter colors for a drybrush highlight after quickshading to make the fur really look good, no matter what color it is. Orks are probably the best for slap 4 colors, dunk and whip and "Job's a gud'un!", furry guys like Skaven and Beastmen need a touch more to get there, even at wargame levels of detail.
