Anime Style Dib by @NightmareNikki (Nikki Star)

This was actually draw before the one posted under. I drew this for the first outline of the Manga characters. It takes place when they are all sophmores, so they look older (duh!). I know I got the hair wrong, which is partly why I am posting this. I'm debating with myself whether to fix it or not because I kind of have it worked into the storyline. The deal is Zim's base was ruined and it has been ruined for years. Since then, Dib didn't need to have his hair back to pay close attention and see extra clearly? That or he just changes it, and then decides to flip it back again later becuase it gets in his way? I dunno, but that's why I ask you, the people. Please give me a good critique, and mention whether or not to fix the hair.
