I would not place windows onto the front edge of your space shuttle, where heat could blow it when entering atmosphere. or make it really different from existing plans.
With these big wings I guess it would enter the atmosphere at a much slower rate, as it has a greater drag. How do you want your spacecraft work? It could even use a special elevator system like in Freelancer or make it a space SHIP, like in Cownboy Bebop where the space ships can also land in water.
