That's a sample found by searching for "acrylic skin tone". There were a lot of quality links.
Two issues that I ran into:
1) I suspect that miniature painting, with the available pre-mixed selection of paints, has a different sense of selecting and mixing color than palette based painting. Pre-mixed paints provide an anchor from which to obtain colors. When using a palette, the starting point is setting up the palette, and mixing from there. Which is to say, how you approach the question will vary depending on which of these perspectives you use.
2) The information is very comprehensive. I had a hard time finding beginner type information. This relates to the fact that I'm a software engineer, not an artist, and what is basic for an artist is pretty advanced for me.
1. Always always use a blended mix of 2+ paints for skin tone. A single-paint tone NEVER looks right. I'll typically start with a 'barbarian flesh' paint and add brown for darker tones, white for lighter pale tones. Adding a little black paint to barbarian flesh can work too - gives more of a grey-brown African type skin tone - but adding brown is safer.
2. Use a wash or ink (mid-brown works for Caucasian skin tones) and highlighting with a paler tone on nose, chin line etc.
3. I got great results with Grenadier barbarians by using Dip Method - paint the flesh in light tones, before dipping the minis in honey-colored varnish - they came out looking like Muscle Beach bodybuilders. I wouldn't particularly advise this for the One Special Mini you're taking 10 hours painting, but if you're willing to take a bit of a risk it can pay off really well in time & results.
The use of the word "blob" may be an indication that your paint is too thick. Most miniature paint needs to be thinned with water a bit before application to go on smooth. It is better to do two thin coats than one thick one.
