further logo design

After 'perfecting' the logo I have chosen I have now decided that I am not sure whether I really like it.  I think it may seem too young and sketchy rather than professionally informal.
I will keep trying and hopefully create something more appropriate.  It simply could be the change of colours. I should imagine, as it is hand drawn type, it needs to be with more sophisticated colours rather than pastel ones.  I think the grey worked better.
