On top of what Femboy said I'd also like to add that you were overflowing mass for a long time, left quite a bit of reclaim over the map, and didn't use your advantages. You had him massively outgunned in navy, as well as air control. you could have taken 6+ T2 mexes using bombers and torps alone.
In games like these it's good to just zoom out, and take a breath and assess once you take over the map. It felt like you were constantly trying to break in and end the game immediately with all the units, pushes, and t2 arty sieging.
