Well, I must confess, the logo is a bit busy. But I have seen and made logos /you can see in my portfolio/ , that have three times more elements. If you don't like it, then this is enough. :)
The truth is, that if you want clean, free of elements logo, you must choose between London icon, or IT icon.
If you want them both, you will have to compromise.
From my point of view, the PY letters stand-out the most, then the eye catches the bridge, then the pointer. This is with this composition. Unfortunatelly this is the only way /other than the ways I made/ that can combine all those elements.
I can try more if you wish, there is no problem.
