Some nice work there. The last one gets destroyed by the photo though.
I'll comment on the Farseer as it's the one I can see the best.
I think it has overall some nice colours except for the red of the inner robe that looks only slightly colder (perhaps not as highlighted?) and more heavily shaded then the outer on this picture and clashes a bit with it. I'm not sure if you meant it to be the same colour or not. Differing in darkness of similar shades often goes well, in hues it's a bit more difficult. I'd probably do it more radically different to make the mini easier to read, a darker deeper red for example if you want to go for red. It would bring out the details of the runes in front as well.
The technique also looks ok. The shading of the inner robe looks harsh though, you could definitely work a bit on the transitions there.
Finally I think you could try to define the different parts a bit more. Emulate the sharp, hard, cast shadows that form around say the pouch and the runes and gems. You don't have to do "blacklining", just use a daker shade of the main colour you use.
