Never tell anybody that you're going for a "retro anime vibe", it makes you look like such a goddamn lame-o when you can't pull the style off, and I'm sorry to say it but that's what's happening with this piece of artwork here that you've posted.
If your artwork truly had a retro anime vibe, people would be able to tell without you having to point it out to them, and if it doesn't look retro enough (or at all) then you don't have as much pride to lose if you never allude to it in the first place.
I suppose in this case it's alright because you're posting it on a board for critiques and so people are going to help you achieve your goal of getting better at recreating retro anime, but I'm mostly talking about posting this kind of stuff on social media.
I mean I could be wrong about this for all I know, and maybe I'm just being a sperg, but personally I find myself scoffing over most artwork that attempts to be "retro 80's/90's anime" because so much of the stuff out there looks so incredibly amateurish.
Successfully pulling off an established artstyle is less about copying the main glaring tropes (such as the "floofy" hair and giant eyeballs) and it's more about getting the little things right and spending a lot of time getting to understand all the tiny nuances that amalgamate into a perfect representation of the artstyle. Don't just take inspiration from the most exaggerated and popular examples either, it's good to have a wide range of influences on your pallet. The kind of people who only look to Sailor Moon and Urusei Yatsura for inspiration are those who will stagnate and not make it far in their pursuit to obtain an authentic retro anime style.
Also it shouldn't have to be said but practicing general things such as proportions and positioning will help you a lot here, because as it stands now, the art the you have posted feels stilted and flat, and that mostly comes from the awkward looking pose and the unnatural proportions.
Work on your lineart.
