Great first try!

I found there's an a capella track, might be cool to study if you want to pick up some of the mixing aspects they did as they did mix these vocals extremely well.

It is pretty advanced mixing though. I can tell you all about if you want but I would recommend starting basic - my first recommendation would just be to add compression at the start of your chain (I posted a thread earlier about how to adjust settings) and then add on a stereo reverb as you did but pick a medium length preset (between 1-2 sec is pretty standard if it shows you the time) rather than the short one you chose (which is fine, but less common and effective). A well tweaked compressor followed by a well tweaked medium size/length stereo reverb (make sure you use a stereo track) is, in my view, "home base" for any vocal mixing.

Didn't know my diction was so bad... shit...

Well, it could be my ears...lol

What Phil means about dynamics is WITHIN phrases. I remember I initially used to think about dynamics more as like verse softer chorus louder etc. as musicians are trained to think that way since that's how sheet music dynamics are usually presented. but that doesn't make enough impact. You need to have micro-dynamics (within phrases) as well as macro-dynamics (the changes from verse to chorus, etc). For most styles at least, definitely a song like this.

I've been working on the micro-dynamics they are REALLY F%*$^(N HARD lol

Btw, although may be biased because I'm just becoming obsessed with him lately, I think Jeff Buckley is a great example of most of the things Phil mentioned you to put more thought into. It's also really helpful to listen to live versions of his songs

Second take is a little bit better at following Phil's points but I could tell you were thinking about things analytically and as a result you kinda lost the emotional convincingness of your voice to my ears, so ultimately I personally enjoyed your first take more. However this kind of analytical practice you're doing that's showing up in the 2nd take is really good for developing because it helps you make real technical changes quickly so you should definitely continue on it with this song for now. And then later on once all these technical changes are happening, you will notice it sounds right, has more dynamics, body connection, effects, etc. but still doesn't FEEL right listening back - at that point you go on to practice putting the technique to the back of your mind and just singing it like you mean it, and then maybe you compromise the SOUND a bit again and then it's a game of balancing the technique and the emotion and eventually you get them to click together. And you keep building like this in layers. You probably knew all of that already though LOL i'm just rambling.

I will let the others comment on further technical tweaks as they can all sing better than me

The only thing I did notice right away is that think increasing the vocal weight sabotaged you a bit especially for a song like this that IMO doesn't really need it. But also it sounded like the extra effort you added did not benefit the sound. However I'm sure you could practice adding vocal weight with a teacher who can target that specifically and they'd help get it happening correctly in your voice. On your own you just seem to be approaching it incorrectly, that's my hunch. I wish I could tell you how to do it differently but being a naturally bigger voice I don't have much first hand experience trying to add weight to my singing. I tend to think more in terms of adding intensity anyways, maybe that little term-swap might help you approach it more organically.

LOL @ the "sexy beast" bits
