Brand New!!!! Looking for Vocal Advice/Direction (recording including)

Hello, sorry if you get these kinds of threads all the time. I'm brand new to both gearslutz and really the music production/recording scene in general. I'm a vocalist who sings all type of music, but I have no clue what to do with my voice when it comes to recording. I currently am recording with a Audiotechnica AT2020 run through a M-Audio MBOX II into my ASUS laptop (using the latest version reaper). I feel like whenever I record, there is no fullness of sound our anything and it's starting to make me feel like maybe I just suck and the mic is telling me. The sound is very dead to me. I wanted to ask you guys what you think I should do to achieve a strong and full vocal sound in my recording. Is it my performance or is it something that I can achieve through proper audio editing? I've included a quick recording that I just made of The Weeknd's "Crew Love" (Only the first verse and chorus). I added no plug-ins to it, that way you guys can look at the actual performance and see what can be done to it. I'd really appreciate any help. I've been doing a lot of reading and googling so I understand what a lot of the different terms and stuff means, but it's been really confusing going from reading about a theory in a book to actually attempting to apply it to the recording. If I could start by getting a little guidance, I feel like I could go from there and experiment. Thanks you guys.

I had a listen... my initial thought is that you're recording the vocal in space that's not treated, you can hear a bit of the room reverb on the vocal track and that can make it sound "thin"(in my experience). Where did you record the track?

The old blanket over your head and mic trick 

I suggest drinking a nice bottle of wine then covering yourself and the microphone with a thick blanket and trying that. I find I always get my best bedroom vocal performances this way. You can always try and turn your closet into a vocal booth - search around on the internet.
