this is a great coloring of the manga panel :o) honestly one of my favorite panels lol i love the way paru itagaki draws haru's faces hahahah

Thank you but I actually didn’t colour in the manga panel. I drew all of that on my own. However, I did use that specific panel as a reference.

itd probably be more ethical to link the images your referencing because your copying line for line from the source material. generally artists use several references and transform it in someway, but your gallery is just recreations straight from the panels. if you drew something and someone recreated it like what you are doing, im sure theyd be upset. shorturl.at/lABOQ heres something to consider. also you didn't draw it all on your own if you had to use a reference to recreate every single line, if you didnt have that reference then you wouldnt be able to create anything
i can point you to several resources that would help your artistic skill, build a visual library, develop your own style etc. but if you say no and continue to rip manga panels to pass as your own work then i see what kind of person you are.
