#43 - #47: Thank you for these entries. On initial look, each one of these have a lot going on. A bit too busy for the message and image we are trying to convey. I welcome some edits or other directions!
#58, #59: Thanks for these additional submissions. I appreciate the effort. Both of these are quite busy...similar to your first designs...have a lot going on. The stylized certification might be all that's needed. See what you can do to create a complete logo using just that element and some more interesting type treatments or just the name. You can even make the certificate ribbon more abstract so as not to be really obvious.
