Like the font. Looks good also to mix with the grey and blue. Not sure about the bird though he/she (?) is cute. Also when making the T like that i could be mistaken for a cross...
#14 Still not happy with the bird. When resizing it down to 154px width (see brief attachment jpg) it's very hard to see the details, and i'm not sure if i like the idea of a bird as character.
I think I'd like more body, the style is perhaps too clean.
I'm sorry, but #19 and #20 is not what I'm looking for at all and a step down from your previous entries. Read through the contest brief again, it might get you back on the right track.
Keep on, but these two goes into the not interested category, sorry.
