Greeting to you!
I am a newcomer to the CFC and have recently read your topic, Shiro's Works (Feb 26, 2005, 01:47 PM), I do have some comments on your leaderheads personally, though they were excellently made ad I am willing to practise them in my scenarios, but I hope that there are more better and better quality works, here are my advices that maybe harsh:
Firstly, the backgrounds can be more futher developed, the place where the leader is standing is also important, try not to let them standing in front of a national monument or modern city screens, they seemed like photos.
Secondly are the make-ups and clothings. The leaders' garments should be as advanced as possible, not looking like as a villager or townspeople. Also, the females' clothing can be fitter to a national leader more appropriately as a solemn figure
