Yes, i've also approved a lot of cartoonish icons. Many of these are awesomesauce.
U say that u're drawing stuff from anime, right?
We are a Warcraft related site, not an anime related one.
So, when we upload resources here, they must be useful for the Warcraft realm in some way.
Also, u say that "One piece fans will know those", yes, but we don't upload stuff here exclusively for "One piece" fans, we upload things here mainly(but not exclusively) for Warcraft fans.
So it doesn't "bothers" me too much that ur fruits are cartoonish. It "bothers" me that the shading is lacking, that they're looking flat, most of the details seem like they were drawn on the surface of the fruit and not being part of the fruit itself.
