I Like the artistic approach :)
good comment thnx
WOW !!! Great style! I like it
glad that u like it
I really like your background! Maybe I would used a contemporary sans typeface just to get a good contrast and bring the poster closer to the science theme. What about a Titilium light for example?
Oh, something different, thank you for that already ;). I appreciate how you didn't even try to make a classic poster with a point and a message, but instead just went down the plain fun and artistic route. I agree with Davide on the font though, a simple sans serif would probably have been a better choice. Maybe you'll get a chance to change that if the client decides to buy it :).
Nice expressive idea! Lovely!
