How about some feedback on this poster?

Let me know what you think. It's the first piece of work I've done that I've felt really proud of.

Good work on this one. Only one thing I would change is the font of the text in the top right. I would make it match the font in the bottom left. Generally you should only have up to 3 different types of fonts on a single poster, magazine, newsletter, etc, etc.
Overall I like the design and nice work on that octopus.
