nice starting man, i think we all start by using whatever tool we can find.you have to take courses of photoshop (i do not recomend that) :P or start by following some good tutorials. you can find the best website of photoshop tutorials here PsLover

after you learn pretty good photoshop you can start by creating what you have in mind, and now what you can brush or do with an effect... you know what i mean :P hehe

oohhh.. and i didnt like the first one. it kinda looks like windows logo :P lol... i hate windows ^_^
