I like the concept a lot! Especially for #76. My thoughts would be: is there a way to make it a bit more feminine? I like when the gray has a slight blueish/green tint to it as well....and finally is there a way to make the one in #76 look like a camera inside? just subtle...
Oh, i like the use of a little color in the last two designs with the camera. I think my favorite look of your is still #76, although I like #79 a lot too.
The more I look at #79 and #80, I feel like the shape reminds me of a suitcase rather than a camera. I think we need to work on the camera shape/feel. Also, now they are a bit too green....a little more gray-ish
#76 and #152 are my favorites from your designs. I would like to see them with a slight use of color - not quite as green as you used before, but more grayish-blue/green, while still using some regular gray. Could I also see some different fonts? Maybe one where the thickness of the letters varies a little?
