Thanks all
These figures have been a long time in the making. The Tudors were also when I first started but after a while I got into the swing of using a few sources to work out their banners, heraldry, retinues and could usually find out a bit about their role in the campaign. Over the years for quite a few of them I also visited their castles, homes or places of rest - it felt strangely affirming to see their heraldry and badges, i felt privileged to know quite a bit about them. The net result was that I was reasonably confident to give a fairly accurate portrayal of these men.
As for the French, it really has been the opposite, like fumbling in the dark, I haven't been afforded any of the above so scouring libraries, the web and perhaps overall pestering people to try and help me, it's out of my comfort zone 'research' which goes a bit like this 'i notice you're french and like miniatures....can you help me !' the response i've had is great to the extent that people now just email me if they see anything that may be of interest. The power of the web really does help us solitary painters feel part of something.
I'm not a gamer so i'm prepared to wait until I think I have as much as i'm going to get before committing to producing a unit which will hopefully meet that brief of as near a historical depiction as is possible with the figures and information available.
Just reading that back sounds like i'm hoist by my own petard but I think everyone's collection whatever the period feels so much better and personal if you've made it your own by researching particular campaigns or personalities. I think my problem was I started with that then tried to find miniatures rather than the other way round. I don't think anything i've done was simply straight out of the box ! it makes me wonder why I do it sometimes but i can't seem to keep myself away.
So, er - that was longer than I intended but thank you is the short version !
