Interesting variety in the silhouettes! You might wanna number your concepts though so it's easier to state which concepts people refer to.
The two silhouettes on the far right and the bottom-middle-left concept catch my eye.
You're right. I forgot that there may be suggestions.
I myself am inclined to the silhouette in the upper-left corner.
Upper left, 2nd one and bottom right are interesting to me but yea 1st one works well, if not that both 2nd and last work well together in my head anyway. Nice
Creative designs for sure. I like the first one a bit more so far.
