Hi all

I have been working on a WW2 Maus tank for a personnel project but having some trouble modeling the front of the turret.

With the first pic can someone tell me if this professorial (Is it meant to look or be like this) I could find another way on how to model the front.

With pic 2n3 could someone tell me how I would go about modeling this highlighted part. I am stuck at how to go about it. I did try a cylinder on its side but was unable to get the rounded corners at the top and bottom and also the straight parts.

Thanks
