They weren't bad (the three poems that is). Please don't take offense to this, but I'd highly suggest writing in a program with a spell check and proofread before you post. All three were fraught with not just spelling errors, but simple typing errors. For example, in 'Limits' you said "The thongue lik\cks" instead of what I'm assuming you meant: "The tongue licks". Moving past that however:
Cries of a Valkyrie: I kind of get where you're going with this, and I like the direction, but it's lacking details that really make me care about your subject or really help me understand what your goal was. Also, it feels a little chaotic, like not a lot of thought went into it. I guess with proofreading you might realize this and adjust.
Dead Space: First and foremost, "Makeshifting your appearance" this line confused me. I had no idea what you meant. I assumed this poem was based on the game, which helped clear it up a bit, but, again, it was pretty chaotic. Taking a minute before you write to think "What do I want from this piece" or "What do I want to present with this piece" never hurts.
Limits: I liked this one the most, though in a bit of an indirect way. The first group of lines and the second group were both decent on their own, but I don't get the connection. Maybe clarify? Again, details would solve this problem.
Well, that's just my two cents. I guess the big things I'd hope you work on are proofreading, details and at least a little bit of planning.
