Looks like the application you are using to view your model uses a perspective view.

ok thanks! another question. do you suggest to modelling in perspective or ortho view?

Purely personal preference. If you are making an object from mechanical reference images, this would most likely be better in orthographic. Remember though that the real world in not orthographic. As you have seen something modelled in orthographic view will not look the same as it would do in the real world.

I use a combination of both.

ok thanks!
