Hey Kate, I actually like this! Very creative and artistic. Love the color choices. I'm normally the one who would say this is very hard to read, which it is by the way, but when I first viewed the poster/bulletin, this is what I saw!
So it's very effective the way you've provided two ways to read the poster.
I like it too. Maybe changing the tones from bright to a sort of pastel or slightly different shade of the orange would differentiate the word better. But I think it depends on the audience. It appears to be for general public consumption, so to speak, but the fact that reliability is stated in the very first line, it should be more obvious. I like the colors too. Orange and blue are complimentary and this is subtle by the shades you used, but they work well together. I wouldn't suggest changing a thing.
I think it's a lovely design and very eye catching which is a huge feature of creating a poster. Get their attention, then deliver the message. Veddy goood.
