Hi, #18 is a really nice solution. If you could make the black negative space in the "R" a little larger (just a little). And make the angled "leg" of the "R" thinner to match the thickness of all of the other parts of the "E" and the "D" and the "R".
Whatever you do to the negative space of the "R" shouldn't look too much different than the negative space in the "E". After you loosen up the "R", you might have to adjust the "E".
If these comments don't make sense, please ask for clarification. I'll try to check in tonight.
With number #25, I like the concept you are going for with the racks. Do you have any other ideas to make it represent a warehouse type rack system with cleaner lines?
on #25, can you try moving Pro and Installers on two separate lines and boxing them in with black or red? Pro will be much larger and kind of look like EDR PRO with Installers under. Also maybe try something different with the red lines/areas in the rack part next to EDR. It seems a little busy.
On #25 - can you remove the yellow back ground, replace the word INC with PRO, then the word Installers will be beneath that and justified to the width of the entire logo?
