Absolutely lovely figures you’ve done! I always somehow feel guilty over such “cheating”. I’ve done the same thing for WW1 Russians – coloured khaki primer and wash and pick out the various bits of kit and they’re done and look great.
Perhaps it’s my innate thriftiness – if I take longer painting castings the “proper” way, then I might buy less figures!
Which, of course, is completely a false presumption. My unpainted pile would perhaps be smaller, but I think my credit card would continue to be as abused as ever.
