Global comments....1) the LLC is not necessary in the logo. Also, I should have stated that I dont really do high rise office buildings...2) the office buildings that I work on are low rise or mid rise.
#1, I do warehouse buidlings more than high rise office buildings. also, the LLC is not necessary in the logo. #2 looks too residential, like houses rather than commercial buildings....make the buidlings look more like warehouse buildings or low rise office buildings. #3/#4, the H is too feminine, but I do like the combination of the green annd the blue better than just the blue
