Photoshop quick tool selection

[SEAN27051629ug4b]

Using photoshop I am taking a foto from inside an apartment lounge looking out the main french window glass doors to the balcony & blue sky view.

I am doing this by trying to merge / edit 2 photos together but the finished look is not natural and the window frames & curtain edges are jagged

I cannot seem to resolve this.

Any ideas for help please

thank you

Mitch
