Welcome to the site!
So, I critiqued this based on the terms of the "deep, deep love challenge" and then more generally. In terms of deep, deep love it fell short for me. The first section was the club atmosphere and wanting that first dance, all the plans he was making in his head, and then ended with not letting the love fall apart. I kept re-reading, looking for where the love happened, and I couldn't find it. It was just suddenly there at the end with a mention of Cupid and love. So building in more emotion would help to get that across: breaking me/taking me/deep into the heart of me.
Looking at the lyrics more generally speaking, there's some interesting elements. The double meaning of "couple grand" made me smile. In my opinion that would be a better title for this and you could then rework the lyric around the idea of trying to build a couple grand into a big life in both money and love. The strongest critique I have to the downside is that there were a lot of filler lines that rhymed but didn't add substance. Another way of saying that is--Welcome to the Club! If you check out critiques in the various forums you will see that all of us who post have been guilty of "rhyme without reason" at one time or another. Sometimes we're just blind to it and need our fellow critiquers to point it out, or we're just so relieved to have found something that rhymed that we didn't stop to ask if it really adds anything! Examples of this for me were the "man oh man" line, the line about fan blades, and "perfect like 123". Your message will get lost among the filler lines. You need every line to be on-message.
Again, welcome aboard. ~T
