thank you amit and bappy for your comments and suggestions
pagol bhai thanks for the detailed suggestion, I know that the menu has a lot of words but the client wanted the site in Czech language and the alot of wordings in the menu is the result of the same

even though i managed to reduce some navigation buttons and added it in the footer as a text. only the main sectors of their business is present in the menu.
and you pointed it right, I am also not totally happy with the perspective of some of the buildings, i will work on it more to blend all things together more evenly.
