Just a quick FYI - the slogan is "Sounds for slumber", which you have correct in some.
#44 & #47 - Same speaker concept as mentioned above for #39. I think I was commenting as you were still submitting. I'm leaning away from the machinery/speakers.
#43 - At first impresison this is my favorite of your submissions. It's nice to see some other colors, and green works well. I can see this working well on a CD and CD jacket. I'm trying to think how & where I would place the slogan if I were using this.
#45 - This is a pretty nice wave. I'm not sure the font gels with the style of the wave, but that's just my first reaction.
#46, #48, #49 - I've been leaning away from using the sound wave graphics, though it does depict the product. They're not a deal-breaker in & of themselves, but the logo would need to be able to stand on it's own without them. Also meaning I'd want to have them clear enough (which you do have) for me to remove.
#43 - I'd say this might have the danger of being too light, in the end. But the lightness is part of it's alluring quality as well, so not sure if we should change it or not. Just voicing anything I can think of here.
Another note, to get some aspect of water in this, is to play with maybe some water ripples at the bottom reflection area. As if this logo was dropped into a still pond. It should still be pretty subtle, as the reflection is now. If you go for this, do it to your tastes first. It looks like you have nice subtle tastes already.
Thanks for the comments DLF! I will see what I can do with the little time we have left on this. I'm glad you liked # 43. I'm going to try a few things with it maybe darken it a bit for starters. #45 I will try a few other other fonts. I didn't want to get too crazy with the type than again maybe a slight twist might settle well with the wave. Thanks for the input DLF I will get started! Love the water ripples in the reflection idea. That could really work nicely..
Thanks for all the hard work! Ultimately, your original work on #43 turned out to be our favorite of the lot. I appreciate you trying out the ripple effects too. I guess there wound up being a bit too much competition in the reflection areas on most, but #68 came out pretty great. Really tough decision here.
