It was actually nothing. I just created the background image. For the smoke effect, i just applied brushes.
You should try making it look like the smoke is wrapping around the logo. The way the smoke looks makes it seem like it should start in the back of the logo and come to the front and so on. Good job for your piece, keep it up and you will get better in no time.
You did a good job with your first try! btw i am also a photoshop user but am a beginner and my work is as bad not shareable
