Looks good, but as already stated, it's pretty wide. If you want to represent the skyline, make it more noticeable. Perhaps tone down the effects a little, or emphasise the skyline more.
Also, with the text, try to never use that bold times new roman stuff, especially if it's going to be big. It's just such an amatuer font. If you're gonna go basic, make it small and bare bones, like the best mod sig you have right now.
Otherwise, go a tad more more fancy. And place it up higher too.
Lastly, a one stroke black border would look much better.
