*I don't know you or any of your other music, and I tend to be brisk in my criticism, so skip this if that's not what you're looking for. I have also never been a professional musician.*
I liked the first one better. The second one started out strong, and I liked the more distinctive singing, but you didn't seem to know how to end it, as if perhaps you ran out of things to say. Both could easily be on the radio with some fancying up (distorted guitars, harmony, higher singing part, bad haircut). I don't know how close to the radio sound you're wanting to get- you're a bit in the middle. Perhaps you want to slide more toward radio or more toward indie?
If you're asking ATOT for advice on your music, and from what I hear in these two songs, I'll guess you're still working on finding your musical identity. Try recording several versions of each song, even if you have to make a change you think you won't like. You might be surprised at what you end up liking when you listen to it, and you might also find strengths and weaknesses you had no idea existed. It doesn't mean you're a cheap sellout if you experiment with your sound, unless perhaps you end up recording stuff that everyone else loves but you despise yourself for charging for. I personally have a lot more respect for people who sound weird but sing from the heart than I do for, well, stuff that's not that. I'm not necessarily saying you belong to either of those camps, because I honestly don't know.
It's only fair to note that this is not my favorite kind of music, but I hope I haven't let my prejudice through too much. Above all, don't do anything because we tell you to. You've got to be who you are. Music needs to come from the heart, or it's just tricking the audience into confusing sound with music. There's a lot of that around, as I'm sure you've noticed.
You might benefit from reading standard English composition manuals, such as Elements Of Style. Many of the lessons can be used for songwriting as well. This can help you know what you want for your sound in terms of audience, expansiveness, efficiency, innovation, etc. Pay attention to writing exercises as well, and adapt them to practicing writing music. For instance, one I had to do in AP Comp involved writing continuously without stopping for a certain period, even if all you could think to write was nonsense or blah blah blah. I thought my teacher was nuts at first, but it's surprisingly liberating and it helps you sharpen your thoughts.
