we like #27 but it needs to be a solid logo with no stipple effect. It just lacks something in the image and maybe the person needs a microphone in his hand or a laser pointer? Maybe the whole design should be in a box? If you can bring a bit more life to the design we like the concept. Thanking you in anticipation.
WIth #29 it has potential but blue and green look awful and we don't want the stipple effect. It needs to be a solid logo and maybe black and blue or blue with the yellow arrow might stand out? The blue needs to be a dark blue or wven black. Hopefully that helps.
