I see what you are tring to do with the "4" and "a", but it has to look like a 4, otherwise our clients will remember it as "smart" the name is "sm4rt", for email and webpage they have to remember its a number 4. But yes it has to read a little bit like an "a". I think we preffer blue to aqua green. and the ripple effect on letters doesn't make a lot of sence, it looks like somehting about the sea, to wich we aren't related. Also games studios is too small.
#31 is too hard to read. we like the idea of making somethign with the "4" on teh name and the using that as the emblem. The "4" you are using is also too hard to understand, it looks good, but peapeol have to able to undertand it. (better blue than aqua)
