It's...a bit boring, in all honesty.
You've got a Mac OSX default wallpaper in the background with an image of a Gundam character and poorly-cropped volleyballs and slime hemisphere.
I understand that you did it last minute, and it's good that you were able to pull it off, but it's still kinda drab and formless.
The text to the left of the human is too close, needs more empty space between his arm and it.
The text at the bottom of the box is unreadable.
