I like the use of DLF of #16. However it seems a bit busy. Perhaps something a bit different for the use of the DLF at the top would be better. Something clean yet creative. I also think it would look better if the words law firm were spread out along the bottom of Duarte and the side lines were removed. Perhaps if the DLF was a watermark on the back of the logo. I also like #15 how the logo is on the side, if it were a bit more symmetrical, it would be better.
