I did not correct any flaws or fill any seams on this. I thought about doing this, because that is the way I alway build my models. However to be able to fill the seams you would have to leave much of it assembled and that would have made painting difficult. I was more concerned with getting a nice finish. Here is a picture of the hands. You are correct, pre-shading is difficult on a piece this small. I just did a bit, the detail on the hands will be better seen after a wash and some dry brushing.
