These guys are looking pretty good, but
has it on the nose. Your photos are pretty washed out, and I'm guessing don't accurately represent your work.
I'd recommend you try out GiMP (which is free!) or photoshop if you have it to try and clean the photos up before posting them. I took a shot at your cultist photo, and did my best to bring the color and contrast back, but it isn't perfect.
I think the color scheme works, and looks pretty close to how they were painted on the box. it looks like your paint is a bit too thick though. The skin and cloth in particular have a rubbery look to them. You should probably thin out your paints on a palette before working with them on the models.
Keep up the good work!
