I like this ideas behind most of these. Text could use some work throughout all of them but I can tell you've already made progress through just these six sig. I would say keep working and making new ones. Keep up the progress.
they look good for being your first sigs. I would say to keep looking at tuts they are really useful when you are getting to know photoshop and just remember to not give up and keep making sigs. That is the only real way to get better.
