Entry 3 & 4 have the right idea. the "o" portion should be a solid color, pantone 541. the words o'halloran international with the line in between should be in black. I would like to see 'Driving You Forward' in an easily readable cursive.
On designs five and six-the words driving you forward, could you use the same color blue on both designs, maybe bold - to standardize and bring secondary attention to the theme?
Hi Dani, sorry I didn't get to make your changes, it was the middle of the night over here and I didn't get the messages till now, I hope your chosen logo serves you well and wish you every success with your ventures. Kind Regards Keith
