Opinions on Song1: There was too little of an amount on variation. Since your tracks lack any percussion or additional guitars, you might want to try to add variation to your chord changes in the Future. Also, the vocals were poor and the audibility wasn't consistent throughout. I found myself actually annoyed by the material in the last minute of the song. Your song structures could be a little more inventive as well.
Opinions on Song2: The vocals are slightly improved from the first song, but I think you should considering getting some vocal effects to improve your voice since it and the guitar are the only things to focus on in the song. The guitar playing sounds a little more mature as well, but it still deeply lacks variations. And after 3:00 the vocals at that part aren't very pleasing to the ears, and the song ends pretty abruptly, which wouldn't be a problem but overall the song didn't have much emotion to it.
Opinions on Song3: First of all, it sounds like the vocals are stiff and lifeless. The lyrics sound pretty emotional, but it lacks feeling to it, this made me unable to get into the song. It was also too short of a song, but at least that kept it from becoming too repetitious.
Opinions on your music overall: Needs some editing and revision. More variation would make for a much more entertaining experience. You're voice isn't too great, but vocal effects could fix that. Also, You might want to consider getting additional tracks from perhaps a drum machine or guest guitarist because the music is fairly bland as it is. With only your voice and the guitar to focus on, it is difficult to keep interest. Try varying your chord changes, or at least varying your tempo or time signatures or volume/passion/emotion at some points. Try to really feel what you're singing about. It adds a lot to the music. Lastly, a solo or riff wouldn't kill you in a song. It could possible make them more memorable or give your audience a reason to listen again. It could earn you major points in originality too, which these songs lack.
Last of all, I don't want you to think that it's bad music, because it's not. I've definitely have heard worse, but there is a TON of room for improvement on all of these tracks. You might want to try adopting some additional influence to add variety to your mix, and of course don't forget to be more passionate and make us believe what you're singing about. You're tag says 'emo', but I don't feel any emotion from it. Also, another track such as drum machines or an additional guitarist or bassist would improve your songs a lot.
I couldn't make out your lyrics too much, so I don't have any comments for them. Sorry if my opinions seem harsh, if it makes them any less insulting, keep in mind that I mainly enjoy Metal, Jazz, and Classical Music, so I might be a little biased.
None.
