I've been messing around a lot with PS now that I have it and I've been doing tutorials which are making my sigs better. Here's my first with PS 2nd And one I did last night when I was bored I even took 5 mins and made the first one look so much better by just adding some lighting but I didn't save it
At first I didn't think it would do me any good because they would be only teach me stuff for that specific situation, but I learned what different things do, I still don't know what to use when, so I just experiment with everything and see if it works.
Ya you do a bunch of those tuts and then you can start mixing things you learned form the last ones into the new one and it makes everything better.
