the cartoony outline is fine... but then u should at least anti alias it, to make it nice and smooth, now its looking  too sharp and jagged, especially because the rest is kinda pastell-ish and very low in contrast .

I like the leaves the dog's sitting on

Thanks all, but i dont really see the problem with black lineart, i wanted to cartoony look as it got but i guess it doesnt hurt making the lineart lighter brown or something

WHAT IS THIS MADNESS.  A BLACK OUTLINE FROM GRIFFSNUFF?

Love it anyways ;)  White background is okay because anything else might take the ain focus away from the dog and the leaves

 this is great! but i absolutly dont like the black outlines, go for  selective outlining and a bit more contrast and this would be a TOP notch piece!...

Why black lineart? Would work better with a darker shade in lineart for each shade.

Ahhhhh.... This is sooooo amazing!! Dont add antialias or colored bg, the piece itself has a pretty awesome feeling without it. Perfection!

i would add antialias. but looks good anyways.

 i love that dog. maybe try out with an colored background, i mean, not white. it would be much more interesting :)
