Poster design: I only look at fishes that are bigger than me

GoldFish Sherlock Poster

The poster is designed in a way to highlight your tagline and yet sticking to the original concept of the Gold Fish as the main character. I took to using realistic images seeing as you are not looking to use vector images. Hope you like the design. ( The Background image source is lewallpaper.com & The Gold Fish is used from the attachment you have posted here. )
