Hey, it's not supposed to be a criticism, it sounds great! But it does sound modern. I mean, it's got that modern-retro vibe, but it doesn't actually sound like a record from the 70's. No-one would buy that these days!
I remember a while ago watching an interview with a producer at Capitol. He said that he gets people saying "I want it to sound just like music from the 50's!", and he has to smile and nod, even though he knows full well that no-one wants their record to sound like a record from the 50's. It's his job to reinterpret that idea and put it through the lens of modern tastes.
It feels to me like that's what you've done, and you've done it really well. It sounds really good and modern, but at the same time has a really cool retro vibe to it.
