I discovered TH Miniatures a few years ago, when I was really into Rackham miniatures and ready to take my painting skills to the next level.
THM has not posted an update to the site in the past year, and I’m not sure how much longer they will be around. In the meantime, other than the gallery of beautifully painted models, I highly recommend the page on NMM formulas. I made a backup copy for myself, just in case the site disappears, and plan to ask the owner about hosting a duplicate page here.
