Wow...these are some great first submissions! One thing I want you to try...for #2 and #3, try it with the O standing upright and the R laying down. I understand it may not work since the R is inside the O the way you drew it, but perhaps you can find a way to make the O more prominent since the name of the company starts with O. #5 is also very slick...like to see some variations of that too.
