It's pretty basic and I don't mean that offensively. The ghostbusters logo is pretty choppy, I can see some pretty pixelated black areas on it, particularly in the top right and middle left. Another thing I have to note is that the GB logo cuts into another letter although I'm sure you were trying to get it to replace the letter 'O'. Instead of doing a clipping mask with the logo you should of placed the logo directly on top of the 'O' and removed the letter 'O' completely. If you really want to get into photoshop keep at it, but if you want to play COD and just have nice GFX on your youtube then ask someone.
