Do I comment? Do I?
Okay lets see
First one looks good but I recomend that you check the palette you used on the cape of the mug
Second one looks like it has some palette errors, mainly the armor near the chest plate, as well as the hair (this is the mug)
Third
It's hectors armor by the way, the main problem with using hectors armor like this is that it was designed to be shaded black and only black, due to the fact that the darkest part is also the outline, to change this, follow the same method for recoulouring, but change the darker shades to a dark red
Other wise its pretty good
keep up the good work
