Yep, cause more than a style is really difficult find a personal method of use PS for make something; there are really many things that you can do with PS so you need to cut what you don't like make and only focus on what you like do, without thinking to what ppl want that you do
I started doing all that is possible with tutorial but majorly chatting with ppl that did something that i wanted learn, so after i asked always how make their works/effect/ecc. and they teach me (i liked going on a mirc's channel and talk with many of them many years ago), but well at the last i stopped to make things that i didn't really liked or what ppl request to me (cause started to become annoying) and i found my personal style for making sigs and what method use with PS (after 3 years)
So yeah, i like my method and style, but rather than sigs they resemble more a post-cards or something like them
