All of your designs have the "feel" that we desire. #42 and #43 are especially pleasing. Can you please, though, replace the dog with something else abstract/technology/stylized? We intended the name "Pit Bull" to represent "guardian of company data", but it comes across in graphics as an alarm system company -- poor choice on our part. Would rather see emphasis on technology/abstract. Colors you have used are great.
Again I like the crispness and feel and mood of your designs very much. Would like to see something of yours that is more than just an icon with writing beside it. More graphic, without losing the professionalism.
