At least your trying and that is the good part. the text is not very good on this. Look at how people represent their text and try to observe positioning. Text is one of the hardest parts of a sig. So you are not alone. Dont know what the white chalk lines or whatever are supposed to be doing but it doesnt look right with the sig. I would suggest looking at some tutorials and trying to see how they do things and try to mimic it so you can get the basics down. It really helps a lot.
