The actual render of the ninja doesn't fit with the rest of the cartoony style.
I would focus on the direction of the splatters and work on the background and the ground, they are very weak points.
Placement of the text is perfect and the font is nice.
Just take more time.
xJTRx: Your attitude is that no one before you gave "a real critique", this is art and it's subjective, you may have knit picks about parts of this LP and other people may have theirs. Lighten up a bit.
