Too Big for My Blog?

I'm thinking this new header is too big ... and we have a widescreen computer. 
Or maybe it looks too big to me because we have such a big screen!!
I do try and imagine what it must look like on a normal sized screen but sometimes it's hard when I'm planning the look of the blog.
What do you think ?
If it is too big I have an alternative that I was going to use I may try that and see if it's any better.
I don't want to be too big for my boots or in this case Too Big for my Blog :-)
