The page looks very professional, with a nice color, font, and image selection, very pleasing to my eyes. Well done!
My notes of what can be improved is only an approach like a Call to Action with the E-mail box and Submit Button at the botton of the page. A very important aspect of a landing page is how to bring closer your prospective customer, and these 2 items are pretty involved in this concept. Like a final step in a selling point.
I have found a quite good article that explains in detail how to better approach the development of these 2.
I Hope this helps, and wish you the best of luck in your developer path!
