Coding App Icons

Hey guys!

Sorry I have not posted in quite a while. But I'm now working on designing an application that will allow edit html, css, js, sass, less and coffeescript files on your iOS. I also want it to do things like create AngularJS and ExpressJS apps and then allow you to upload the projects you create to Dropbox.

Anyways.......I consider myself more of a programmer than a designer, so I would love your guys' opinion on these icons. Which ones do you like best?

I like 2 the most and then 4 following that.

Thank you in advance!
