I think you did a good job on Wolfy there. Maybe add something to his nails besides straight black though and it looks like you missed a tiny little spot on his left foot between the middle toes as there is a dot of white showing.
great job on the Invisible Man about the only thing I would critique is maybe try to get the lines on the PJ's spaced a little better, but that is quibbling over small stuff.
I painted some board game minis a couple of years ago and found the quality to usually be lower than Games Workshop but you're painting these sculpts so well that I'm convinced these must be of a fairly high quality. What board game are they for?
