I agree with what you have said about putting up your work on forums and getting advice back. My painting improved a lot from getting advice and also looking at other people's models. I'm glad I can also help people as well.

I did think that may have been the case with the skull, it was a bit difficult to see in the picture.

That's interesting you say you get finer control with a fine detail brush over a micro pen. I am definitely the opposite.

Thanks for the info on Testor's Dullcote Codicier Ignatius and Brother Weasel. I will be giving that a try and can hold you both responsible if it messes up my models
