I may sound ( too ) harsh again, but what about just 'slightly' customizing ( a, b, g, m, n, q, r, y ) 'Century Gothic' instead of building a 'new' custom typeface, from scratch.? :) ( Because the logo itself sure could be based on 'Century Gothic'.. )
Otherwise I may add that I quite like it, but it still looks a bit uneven.. ( Especially where the curves 'meet' the stems.. And you are right about the 's', it may seem too narrow and it doesnt really fit in there.. )
