Entry #2 is so simple, yet intriguing. It's very legible even at a small size and I think that a positive. Same comments for entry #3, but I'm not as crazy about the 2 colors only, now that I see them. Maybe try something with Entry #3, similar to what you do with the letter "O" in "MOD", changing the color of either the dot, or the "donut" in the middle of the "o". Initially, Entry #6 was my first choice. It's not as easy to read, though, at a small size. Can you make it "pop" some kind of way, as I REALLY like it's potential. Entries #5 & #6 were just too confusing to read. I do like the change in direction, though, with the blocks.
Hi, thank you very much for your feedback. I will definitely work on them and see what can i came up with to develop the logos. I made the logos in the red backgrounds to show you how the logos will work in one color and in negative. Regards Filipe
