Lowton became new Villa manager Paul Lambert's third summer addition when he joined from Sheffield United last month.
And Clark says that 23-year-old Lowton makes playing football look easy.
He said: "Matt has come in and done really well. Not only is he a top defender, he's a cracking lad too. He's joined and had no problems whatsoever settling in.
"He's only a young lad like myself and he's settled in with our group really well. He's having a laugh with us and that's helped him out.
"Playing-wise, he's so comfortable. He'll be looking to have a good season. He reminds me a bit of Kyle Walker. He's not frightened to get forward and get crosses in. But also he's a good defender. Not many will get past him.
"He's played centre-half too as well as right-back and I believe he's played in central midfield for Sheffield United too so he's got that versatility also.
"He'll be a big asset for Villa, no question about that."
