Not my style of music, I'm afraid. Nor do I know anything about Indie Rock to know how it stands among other bands. However, as a musician-wannabe, I can try to provide some feedback.
General: Overall, I didn't like the production. I know this is just an EP and it is to be expected, but I feel it could benefit a lot from it. Besides that, I can't think of anything specific I'd want to change. At least it's not horrible or too loud or something like that, it's just that it could be much better if the instruments had more presence in the mix.
I like Sometimes and Spooks the most, but can't decide which is better. I feel they are the more unique songs from the list. I think I like them probably because they feel less linear than the rest. Obviously, I like the few progressive elements thrown around. My least favorite is Buy the Ticket, but I don't know why. I guess it's because it sounds more "normal" to me
As for I Will Forget You, my criticism is that I feel like the vocals are harsher than they should be for that song.
I can at least tell that the songs aren't "cheap" like much of the music around. I like the riff duo between the guitar and the bass. It's very well done, especially in Spooks.
I wish you and your band best luck!
