Oh boy, this is going to take a while.
Before I start, I want you to know that I'm typing this to help you make better comics, not because I want to hurt your feelings or something. This is not flaming but giving construetive critisism.
Comic 1:
-Save as PNG, not as JPG. When you save something, there is a panel near the bottem-left corner. Change it to PNG everytime you save a new image. JPG ruines a image's quality so that it takes up less space. It is used for saving images, so don't use it for anything else.
-There are many, many grammar mistakes. First of all, you must use a capital for each first letter of a sentence. Your punctuation is also not very good. Always end a sentence with a period, end a question with a question mark, end a command with a exclemation mark and devide a sentence into two parts with either the word "and" or with a comma. You must also put an apostrophe between "we" and "re". Otherwise it says were, as in the past of are, instead of we are. You must also always use a capital with the word "I".
-The humour is not very funny. The "we need 4000 yen for a doll" joke was random and didn't make any sence and not in the good way.
-Why does Ryu want to travel with Kai when they didn't even know eachother? Ryu didn't even knew Kai's name when he asked him to travel with him. And if Ryu asks anybody he meets to travel with him, then why doesn't he travel in a group of 100+ people?
-Does that girl with the black hair always stand behind the girl with the blue hair?
-Why is that Bonsly gold one moment and brown the other moment?
-I feel sorry for that Metapod. He gets attacked in the back by Kakuna in the back and his trainer is walking away.
-Try to make all panels the same size and line them up in rows. That way you don't have to number them and you don't have to puzzle to know in what order you have to read them.
-Don't make such big comics. The stuff that happened could have easily be spreaded out over 5 or 6 other comics.
-How can Ryu and Kai capture those Poochyena without even fighting them?
-How can a newly obtained Bonsly beat an expirienced Agrron using Vine Whip? And how can an Umbreon beat a Mightyena with Psybeam when Psychic attacks don't affect Dark Pokémon? How can an Umbreon even have Psybeam?
-Journey comics suck horribly 99% of the times. So don't make one.
-Speech bubbles are nearly always better then text-under-panel.
Comic 2:
-Again, the people decide to travel together without even knowing eachother. I beleive Meg and Eric still don't know Mark's and Max's names.
-The grammar is again horrible. Use proper puncuation, capitals and all that stuff.
-Save in PNG, not JPG.
-This one could have also easily been split into 4 or 5 comics.
-The Gym battle didn't made any sence. Although one of them lost, he still got a badge because to other kids, who's names he doesn't even know, won?
-Eevee doesn't learn Counter.
-The four kids are in one town one moment and in another town in a blink? What happened to them between the two towns? I thought this was a journey comic.
-Journey comics suck 99% of the times. Don't make one.
-Speech bubbles are nearly always better then text-under-panel.
Also, don't double/triple/quadruple/centuple post for whatever reason. Use
instead.
