I have a question for Shady 2:
How hard is it for them to draw the characters, and all their different poses? (especially parts like hands, feet and clothings)
Nothing is particularly hard, but most of it is somewhat elaborate. First of all it's important to find a pose that looks convincing enough and not too silly.
The problem with limbs is that they all should be the same size/lengths :D You don't think much about it when doing illustrations, but it's important here and sometimes it's a bit of problem. The most hard item to draw is a mantle, it's a complicated piece of clothing and adding all the variations of sleeves doesn't make it any easier.
Pleated skirts are somewhat problematic, especially since I am doing all the tartan patterns by hand, but I kinda actually enjoy drawing them! Drawing the tartan is a bit of a meditative process.
