Problematic Motion Lines?

Of the comics we have read this semester I found The Mysterious Underground Men to be one of the most enjoyable thus far. Largely, I'd credit this to the variance in types of panel-to-panel transitions and the balance between text and image. One criticism I do have of the work is Tezuka's use of motion lines, which I occasionally found poorly executed. On page 79, panel 2 the Queen is threatening Mr. Ham Egg with a gun following the previous panel in which Mr. Ham Egg charges towards her. In panel 2, the minimal use of motion lines makes it look as if Mr. Ham Egg is sitting in a seated position in mid-air. Similarly, on page 104, panel 3 Soda is depicted as jumping in the air celebrating the destruction of the bomb, but the use of motion lines surrounding his legs makes his position look unnatural, and almost as if he is hovering in mid-air. Although potentially nit-picky I found Tezuka's use of motions lines to be somewhat problematic at times throughout the story. In working to understand the differences between Western and Eastern comics I wonder if this was a stylistic choice made by the comic artist, or if others share a similar critique of the work?
