Logo practice

So, I have very little experience with logos/identity (read: I suck at them), so I thought I’d practice a little. Here’s a few I came up with. They aren’t really for anything real, just me messing around. They’re basically just text-based, not much real illustration going on yet.

And sorry about the over-used, trendy black/gray + cyan color combo, I’m too lazy to do anything more creative.

I’m open to any ideas, critiques, and insults! I just want to learn and improve!

(I mostly only like the top two, but I included the other variations anyway)
