I think adding more exaggerated expressions and making use of like... You know how they do that one thing in manga and anime where the character goes chibi in some particular frames where they're embarrassed or something... Moreover, you can use a slightly rough style in the scenes where you REALLY want to exaggerate something for example when they're shouting... Idk... I just pointed out everything I've seen in manga :/ . Also, I suck at giving advice...
First off- I love the zoom in of the eyes on the third panel! If the focus of the dialogue is the emotion, zooming in on the face is a good choice. Second- I have an idea to make things a bit more speedy :) there’s no rule saying you have to go back and forth between characters on different panels. You can always choose to have a small exchange on one panel, such as condensing panels 1 and 2 with a wide shot to establish the background. Awesome work btw! Can’t wait to see more!
Well,my comics are bad,so i can't say nothing :'> actually,yours look fine! you even colored it (which sometimes takes a long time)I just think you should increase the edges a little bit (if you want it to look more like a Webcomic, than just a comic (there is a difference))
