You have done a great job and lots of work. And don't be to concerned about the image of of the couple. It's not a sold idea yet for me. I would still love love love to see my original idea that No one has seen yet. If I could sketch it out, I would. But i am not artistic at all. I am the the "thinker". That's why I am here per say , to get help with this logo.
If I could have what I imagine.
* The effect of fabric or sheets if you can imagine... that are tangled up together and forming the word Tango.
I may have to just find someone to hand illustrate this first. It may be to intricate to do with stock images.
But all of your work has been impressive and you are fantastic in your design and dedication.
I hope you can see where I am going with this and it comes through in a design. I do hate to settle, but may have to settle on a different slant if I can not get what I am envisioning.
Way to Go FernandoBrandMan!
