Hi Ochie,
Firstly thanks for taking the time out to help me in my quest for a logo for my company. I really like what you've done with the above 3 designs, they meet the brief well. My current favourite is entry #25 as I can see its use as is and also the left RS being used as an avatar. I would be interested to see the use of the number 7 as some sort of a summit, an upward trending graph or the like to demonstrate improvement, do you think this is something you could have a go at?
Cheers,
Seth
