The logo is crisp and clean and something that people will quickly be able to read on a t-shirt or side of a truck. The line below the image on entry 3 makes is seem like that is a structure that is grounded. I like the coloring and shading of entry 1.
Thanks for the change, I will need to look at the coloring of 3 and 13 a little more. 3 seems to catch your eye a little better and that type of green seems to correlate a little more with sustainable building, but 13 has a richer bolder look. I like how you fade to a lighter/brighter color at the peak.
As you know I really like entry 3 because it is strong and doesn't make the statement that I only do one type of construction, but it is also not something that will necessarily be recognizable with the Holland Brooks brand. I really like what you did with entry 100, although it is almost a little too simple, can you try some other variations of that logo? Thanks.
