Your english is good but still there are some errors.
Seventh panel, first narrative paragraph, second sentence. "He was the ruler of wasteland and no one, neither that mouse could change it" See the problem? Change that "neither" to "not even" and "could" to "can". It makes more sense.
Seventh Panel, second narrative paragraph, "but he still not wanted to see Mickey's face around so he began to piled all that stuff away from wasteland... forming a huge mountain called 'mickeyjunk mountain'." Change that "but he still not wanted" to "But still, he didn't want to see Mickey's face around" you see? it makes more sense.
Also "So he began to piled all that stuff away from wasteland" okay for "piled" I don't think "pile" is a verb. You know what a verb is. Pile cannot be used as a verb, it's a noun, now there are some similar verb sentences that are similar to pile. For Example: Arrange in stacks. Pressed Tightly together, or cram. To place or lay as if in a pile. SO yeah don't use the word "pile" it's not a verb.
for this sentence I would say: "So he began to stack everything away from wasteland, causing a huge mountain called 'Mt. Mickeyjunk'." (or Mickeyjunk Mountain, Doesn't matter)
Now for your last three boxes.
The first after that comma "and from it fallen a open bottle with a strange black liquid inside..." Change the first "a" to "an" and take the second "a" between "with" and "strange" away. Thus appears this: "And from it, fallen an open bottle with strange black liquid inside..."
Second box, there seems to be no continuity to it from the first box, "that object fallen on the mountain" It seems as though you started another sentence. Instead of saying "that object" replace it with "had", then we get: "had fallen on the mountain" now try adding this to your first box.
And the final box "and all become dark" Fit's okay but there is a more professional way. I would say: "and darkness befell on Wasteland"
If only Oswald could understand, it wasn't Mickey's fault he was forgotten. It's greedy, immoral men who took him away from Walt. It's a shame Walt couldn't live to see his 'first son' returned to him.
ohhh, everything makes sense now! I always wondered from where did oswald got the giant bottle in wich he imprisoned the blot, I never thought it was the solvent bottle that mickey accidentaly threw into the wasteland
