Are you sure it's too small? It look perfectly fine, especially the top tube length appear to be idea for your height.
My colnago is 1-2cm too small but the top tube length is spot on.
As for the pinarello bar angle, it look fine, personally not a fan of those bar angle where the bottom is horiziontal and the brake lever is halfway down the bar, not very comfortable to rest your hand on.
