We like entries 4 and 5 (entry 5 a little more) - the AAL font and use of colour is good - perhaps not only black and orange though, the green, orange and blue work well in entry 4. Still open to other colours though.
We would like to see some designs with one or more birds featured in the background in silhouette - perhaps different types of birds e.g. parrots, finches, doves etc.
Great job so far.
