I don't care what anyone else says. I LOVE seeing fanart like this! Specifically, I like seeing Zim shown as more alien than he appears in the show. This is for two reasons: 1 - I like deviating from the human form as much as possible, especially when discussing extra-terrestrial life; 2 - It makes it that much more hilarious that people make fun of Dib for thinking perfectly normal Zim is actually an alien. So yeah, that's why I like the theme of the whole picture. I also absolutely love that she tossed in Gir off to the side being normal ol' Gir.

As for the quality of the art, this new style of shading is working out amazingly well. I feel like it is an improvement on your previous art styles and I'm going to love seeing more of it in the future. Just seeing it go from flat colors to shaded and highlighted blows my mind. It's like seeing someone turn a stick figure into the Mona Lisa before my very eyes. While it isn't SUPER realistic to the point where I think you took a picture with your camera, it is still more realistic than you've done in the past (taking into account the fact that you cartoonified it as well). You know what...I'm going to actually go ahead and say this because I believe it. I think Invader Zim (the entire cartoon) would look amazing in your art style. Oh no...my brain wants to see Godith looking down at the Tallest now! The irony and amusement of that scene!!! Made all the better by the fact that you're smarter than them too.
