OK, I'll try giving you more feedback. As I also realized a few things along the way. However, as I mentioned, I am not the one that will take the final decision. I can tell you which ones I am comfortable sending to him, and which ones doesn't meet the requirements/expectations. So far, what I like about the ones received, is the fact that it remains simple, but looks professional. I realize that the font has a lot to do with it. It needs to be a combination of a great font, and a great logo combination & creativity. Keep in mind that their logo could mainly be printed in one colour (on their products), so yeah colour gradient looks good, but it won't affect the final decision.
In brief, great font...be creative...stay clean..and make it look professional. I want people to go: "huh, they hired professionals for the logo...it wasn't made in an Excel document..."
Do you guys follow me? I apologize if my English isn't perfect, English not being my first language...
Anyway, keep sending your logos, I am satisfied with what I am seing, but not head over heel.
