Human Faces Screenprint

I have been working on a screen print the past month or so. After having to re-correct lines, ext. It has still not turned out successfully, very crooked, very frustrating. It is based on a drawing I did a while ago.There are two here, the top one is as close to right as I could get and with the bottom, the line is slightly off, I kind of liked it though, for all its faults. even if I did manage to get the line right I would still have to redo the whole thing has its all very crooked through out. If I remember there are six colours in this print, plus a light glaze to tone down the background.
