Walker has won a first call-up to the senior England squad.
"It's an exciting team," he said of Villa.
"They play good football and keep a lot of possession and we're good on the counter attack and good at breaking which is all about my game and I enjoy it."
Walker also explained he is happy to be playing regularly in the top flight and hopes he can continue that at Aston Villa, adding: "It's always good to be in the Premier League and it's good that I'm catching the eye out there.
"It's been a bit of a whirlwind month. I was playing at QPR a couple of months back then I've come up to Villa and playing at Villa Park in front of 40,000 people every other week so it's a nice change."
