When I had a go at this myself, I was trying to work chain links into the CW as well. Your's looks so much better than anything I did. Still not quite "there" though. Not sure, but I think the links in #16 are too small. With the tagline "strengthen your supply chain," I'm looking for more industrial strength chains rather than jewelry chains. A helpful strength. In #15, the "W" looks good. Is there a way to work the "C" into that without it being too much? I also like the font used. I'd like to see a little more color or tone. Brighter? "Bright" as in smart and innovative solutions. But not shiny.
#18 is a "better" chain, but it's not working for some reason. I can't quite say why. Maybe making the letters out of chain links is a cool idea that's just not going to work well in practice. Not saying I won't be open to other attempts, but I'll give you the courtesy of letting you know sooner than later that it would really have to be a 'wow' design. Maybe switch gears and try something else? The orange isn't working well. Maybe too much? Or doesn't work with the theme?
