Out off all the entries yours is close to being my favorite.
I like the font style use for "iLock" and Simple Smart Secure ! I like the colors scheme. Especially because everyone else used black and red 95% of the time.
Try a version with Orange and Black...'
Try the same image of a lock, but not the effect you have on the lower right side portion of lock. Also, try a version of the lock with "light bulb" embedded (white background) into Lock.
Thanks for the feedback, I can't add a bulb since other designer has already use it, i've made another concept, the stripes behind the padlock as informations that protected, don't worry about the transparency, it works well in any background colours,
Your close to winning this thing... Honestly. Love the font style, but the Lock "Peel back" look is not working all the way for me. Try just a solid filled in lock image, maybe imbed a simple image of person into the lock some how to represent the "i" .... Light bulbs are good ideas to imbed into the lock also....
You know what looks good... competition is almost done. Let's make you the winner. Get me something different options to work with you on...
