Hi, again! Thank you for Final Round!
I'll do my best for You to achieve Your goal in selecting Winning design. I'll work on refinements of my design, and according to Your suggestions, of course!!!, ...

Thanks!
My idea is based on the top things to communicate, a safe place to express and love & courage, so I created this heart with key, secret place of teen emotions, so close, but mysterious. I hope that is more clear, now. I am open for all kinds of refinements and feel free to express Your ideas, of course. It is my pleasure.
I am looking forward to Your further suggestions!!!, ...

Hi there, this is my idea for Your logo design. I think that is corresponding with the description of the organization and its target audience and top things to communicate from design brief.
I am looking forward to Your reply!!!, ...
