The artwork here is great, I love it. Great use of color and simple forms to tell this little story.
BUT, I just can't get over the text bubble. Maybe you should remove it? The title is enough to relate the humour, the text bubble, to me, seems out of place and unnecessary. =)
"We, the Dreamers, are thus alike.
For our dreams we will fight, and we'll write
the future history less bloody than the past,
with our dreams we'll build a peace to last!"
