The main purpose of the landing page is to get user's contact information. If you want to improve conversion rate for this page you have to eliminate all possible escape paths (this includes all buttons except one, navigation and links). I high lighted them on the picture.
I also like to design a Landing page together with a Thank you page (the page that user sees after he/she submits the form on landing page). On the thank you page you're not only expressing user your gratitude for providing contact information you're also guiding user further to your website. Here you need to show all the navigation and it's also good idea to suggest a further reading or links to community forum etc.
I'm giving you:
5 for design because I really like it.
1 purpose because you not reaching your purpose (which is I believe to improve conversion rate), you're loosing potential leads on escape paths which highlighted on the picture;
3 for originality;
3 for engagement.

But make sure you show it on the pairing thank you page.
you'll loose you lead here
I would make this button (seems like this one suppose to submit form) the ONLY button on this page, and make it red and big like #3
But make sure you show it on the pairing thank you page.
Make sure that logo is just a picture not a link to the home page
