Okay so I have at least three sketches scanned onto my computer, but I can't seem to get them to look right. My lineart looks TERRIBLE! You have no idea how many tutorials I've looked at. I just can't seem to get it to look right no matter how many different ways I do it.

Whenever I do it free-hand no the lines just don't look good :/ I don't know what to do. I want to post it up and everything because I've done no art for ages, but I don't want to post up some half-arsed work.

Help me?
