Here are my initial thoughts:
1. It's too big for a header. You're even forcing part of your slider below the fold for many screen resolutions. The result is valueless white space near the top.
2. If you love that block look, you could keep the logo but perhaps have an alternate for the header. For instance, you use that for the favicon and other areas but for your header, you have something that's more horizontal and real estate conscious.
3. Your website's URL is thebeholderseyes.com but the letters in your logo are behldrseyes (no "the", "o", or "e"). From a branding and marketing perspective, I would align them.
