Luckily I read the comment below me suggesting it was 7/4, cause otherwise I would have likely had a hard time grasping the signature. The reason is that you seem to divide your time into two parts: 7/4 = 8/8 + 6/8. This 8/8 makes you think it is in 8/8, and then the second part of each measure is shorter. I did this too in my entry, so I am kinda afraid that my entry is going to be equally hard to grasp! Overal though, after you grasp the time (which was really not as hard to do as I make it out to be here, don't worry), the song feels really solid. Especially in the later parts of the song, it flows nicely. Well done :D
