Link vs Mario

Okay...this one is actually quite a cool scene.

The effects are properly made, so are the sound effect at the end.
The shading is nice too, as you actually made a goo use of the properties of the pencil and add all the details of both designs.

If I actually had do point out something you had to work on, is the proportions. It's not by a terrible margin, but some segments of the drafts feel off, like Link's shield in the last panel for example. Plus, while the shading looks nice, when making dynamic scenes it's important to make the shading, well..."dynamic" too. If you check manga battle scenes like the ones in Dragon Ball, you'll see the shading at times becomes part of the dynamic lines as well. But oh well, that's at least my take on it. Nice work, pal.
