Hi Ivesons,
Just thought that I would add my five penny worth!
Generally I like your logo, you can tell that it has been designed by professionals as the text font on the logo is crisp and well defined, this is the most important part of any logo. Your text is also a good size in comparison to the overall logo.
I am not so keen on the stars though as they do not flow as well as some designs, but they are bright and well defined.
Why not pay a professional to do their job. Not all window cleaners have Jeff's natural ability with graphics programs!
