The home side won the fifth Test at the Oval by an innings and 244 runs to win the five-match series 3-1.
The batsman, who was England's top scorer with an unbeaten 149 in the team's only innings, told BBC Sport: "It's always nice to score runs but to finish the way we have was very pleasing. To bounce back the way we have has shown a lot of character, the guys had to dig deep.
"The winter was not a highlight of my career, but it is great to come back and score. I was just looking to survive in the winter but now I'm looking to score and to put the pressure back on the bowlers.
"Hopefully things can keep improving as it's a long time till we play Test cricket again."
England dismissed India in their second innings for 94 in less than 30 overs earlier today.
