These are really cool looking and you definitely incorporated the "bits" and "landscape" concepts into the design, which is very clever, but I'm not sure if I really love them like some of the others that people have posted. I can't really place my finger on what I don't like about them though. :-(
I like the font in #26 better than #27, and I do like the use of the landscape in the imagery. The only thing I can suggest is to go less abstract with the shapes, and actually make it look more like something relating to my main business (building software/websites). For example,
http://www.iconfinder.com/icondetails/36826/128/program_window_icon. I've been getting a lot of abstract designs lately, and I'm starting to hope for more pictoral designs.
Also, I looked through your portfolio, and I really like what you did with Iron Sight Group and Nexul, if that helps any.
