Enter - Logo Design

Enter, a B2B Cloud Business Service.

Been working on new logo design project for a service called Enter, a B2B Cloud Business Service.

Here are some of the first explorations for this project and I'm loving the simple E monogram which also refers to the Enter key on a computer keyboard. My client asked for a fresh approach with colors (WhatsApp-like vibe) and give it a friendly look and feel.

What do you think of these first directions and have you seen a similar mark been done before?
