I'll play around with it. I don't think it's too close personally. I wouldn't look at that and think TB, especially because her logo is the mirrored T and this design uses both initials. Thanks for the feedback.
No worries. Works equally well on white or on most other colors. I normally supply the logo in both color and black and white, so you would have options with your background color and could use the icon as a watermark on photos as well if you wanted. Please let me know if you need anything else.
