Hi Adam,
I usually prefer happy songs over sad ones, though both have their place, of course. What I've written below is based entirely on my personal opinions, so keep that in mind. I'm no expert.
1. The sound is pleasant to listen to
2. It did remind me of sitting at the truck stop smoking cigarettes and drinking coffee in my [very long ago] college/university days
3. I didn't think the lyrics were cheesy
4. I'm not a good judge of whether a song is good or not. This reminded me a little of Bob Dylan. It had a sort of droning effect, as the melody stayed quite similar throughout all the verses, choruses, and bridge.
What I think is good:
1. The way you develop the feel throughout the song--not as easy to do with one instrument and a voice as with a band or orchestra, so good job on that.
2. The lyric: it's unconventional, sweet, and nostalgic rather than sappy and predictably lovey-dovey or "I'm so sad because I lost my honey".
What I think could be improved:
1. The melody: It's very similar throughout, as I mentioned above. I recommend a more uplifting, contrasting melody for the chorus and something even more "up" for the bridge.
2. The structure:
a. The tempo feels a bit slow and sad for a happy song. Happy songs can be slow, though, so the cheerfulness could be achieved, perhaps, another way.
b. I'm a fan of prosody, so I look at things like whether the song is "stable" or "unstable" and whether the structure of the song supports it. I would consider your song stable, as it is not portraying sadness or conflict. Perfect prosody would suggest using uniform line lengths with even rhythms, even numbers of lines per verse/chorus/bridge, a major key (you got that part), and perfect rhymes. Now, I don't think it's necessary to be a slave to prosody, but I think it's good to try to lean in that direction.
All that being said, I don't think you need to tear your song apart and try to meet all the "improvements" (in quotes because this is, remember, all just my personal opinions) I mentioned. It's just food for thought and, if you're still working on the song, you could consider how you might incorporate some of these ideas.
I hope something here is helpful to you.
Sincerely,
Vicki
