Feedback needed

Help! Feedback needed…

It's been a while since this shot. As you can see I'm still not done with my new personal mark and right now I'm struggling hardly with it (in my opinion, design something for yourself is the hardest thing you can do as a designer …).

Here are some of the many concepts/ideas and what I'm kindly asking you for is some feedback, regardless if it's "Oh, they are all shitty", just a personal preference or anything more in depth. Just feel free to write anything you have in your mind in the comments :)

I tried to do something with my Initials or with a connection between design and code (since I do both).

I appreciate any feedback in advance!
