Depends, maybe a bit too fat on the wargames table, but as part of a diorama and viewed from afar they're probably fine.
Besides, I still have the odd Minifigs among my 20mm figures which I bought in the late 70s when nothing else was available (Personalities, 95th Rifles, 52nd Light Infantry and British Light Dragoons and Prussian horse). I would have preferred Les Higgins, but they were hard to come by where I lived. I don't use the Minifigs cavalry anymore but Boney and Wellington still stand out big, proud and most certainly larger than life (making good artillery targets too :relaxed:). So you may say I have a rather broad approach to the subject, I guess ... :wink:
