Really like your designs. I can tell you are a master of your craft.
#16 - I like the layout very much. In addition the logo has a great direction with the tech/modern feel. Colors too gloomy or dark though.
#5 - Love the layout and direction on the logo. Currently though I am looking for a logo that speak some of the direction of the company. This is just a really cool logo. Nice work, but not what looking for with the logo.
#15 - Warm logo and color choice. Layout not preferred. Please make wide not vertical.
