There is zero depth,almost no blending and many elements don't fit together.
1st sig:
Naruto's render has been cut off horribly,it's also too sharp.
The shadow effect you added ruins the image.
Fonts don't match well.
2nd sig:
Teemo's ear has a hole,both ear and foot are cut off.
Everything is covered with a noise.
Suggestion to improve: Watch more tutorials.
