Good start. #10 looks like "CDR" "PRO INSTALLERS" is a little hard to read, and this logo would have to be used smaller in some cases. I like the horizontal line that you've used as a connector, it looks like a shelf. The "E" and the "D" look like they have a little more visual mass than the "R". It might be due to the contrasting color of the "E" and that they both have broken or negative space and the "E" doesn't, maybe the "E" could be altered to be 10% or so, wider? Or, maybe try taking a slice out of the "R" similar to the "D"?
Hello Kromosom, To #11, will you try adding one "slit" in the "R"? Either at the top, or just above the horizontal line in the middle of the "R". Same size as the 2 white "slits" in the "D". Don't delete #11 though, just use it as a starting point for these options. Thank you!
