The scale is probably something like 75 mm ; and they hair are made with guitar string . ( It took my about 3 hour for the hair )
I agree with your critics, they are right . The torso look strange, espectially on a picture , the problem is probably not so important with the miniature in hand because you can turn around and see the miniature on different angle . There is also a problem with the T shirt wrinkles, they are not correct and realistic .... But I am happy to finish this miniature, It was on my work desk for a too long time !!
