Hello Khonner, I was passing by (read all of your wip) and wanted to tell you, that you are improving tons from the first post!!
Above all, I like how you pick your colours, but I also like that you are a fearless painter, and have no problems on painting 28, 32, 54mm, or I think even more (75mm?) with some of those busts, jumping also from a finely sculpted pinup to a "stoney skinned troll" should be not really easy, but you have done it without problems. ^^ I could not do that just as easily as you do!
The issue I think you need to work the most is your colour transitions, on some of your minis they are good or really good, but on others they are a bit abrupt, like if some steps where missing, I you understand what I mean.
I am trying to give you my two cents of how I have seen your progress so far, and wanted to leave my opinion for you to consider.
Forgive me if I sound a bit silly/rude, because english is not my mother tongue, in fact writing/reading here is helping me to improve it xD
