Hey man. I'm really liking this one. Your main competition is this guy. He has working the celtic design into his. If you could do something like this I would be much happier. This is the his. https://www.freelancer.com/contest/Design-a-Logo-for-My-Website-52853-byentry-2245147.html
Here are some images of symbols that are celtic themed.Maybe if you take out the controller and add in something like these.
I have added the celtic patterns in logo, but my suggestion is keep the logo simple, if you want celtic patterns. Later on if you have the banner project we can add on the banner. Just a suggestion. but we can do more in detailing ahead. It is almost 11pm here but we can work ahead for your logo via gmail communication.
Thank you for your trust and feedback.
