Yeah, I think I have the chaulkiness under control now. Not solved, but better. I'm thinking of doing the Uruks differently as well, that was mainly a test to see how I liked the hobby before I went wild and bought a bunch off ebay. (I have a huge backlog now - mainly Rohan / TT of course)
Thanks for all the advice, it's always welcome. I'll certainly keep it in mind whenever I get a chance to paint again.
BTW, I have been mixing my own colours à la the
guide by Temet Nosce. It's not a great guide, but a good place to start. For instance, the Flesh tones are excellent - for painting carrots.
