I like the background, and his mouth. *thumbs up*

f--- you, too, then...

Okay ya'll here's the scoop:

I just couldn't include the faces artistically. It's still there, just hidden. Thank you all for your comments!

is this person talking on a phone while blood splurts out the back of the head?

it could just be a fat pikachu

well the lineart is ok, but the coloring does no justice to the piece. The grass is alright, but everything else, especially the textured brush crap with seemingly random colors around the edge seems poorly thought out. You may try just a solid white or offwhite, or continue the grass and sky to the rest of the piece.

On the dog, the main problem is all those white bits. I would suggest start by coloring on a layer between the background and the lineart, and use a solid brush to completely fill in the character (not the fill tool!), then use a darker or lighter brush and add shadows/highlights to give it depth.

Last of all, as I've mentioned before, the copyright notice is really tacky. Personally I'd leave it out altogether until you're actually good enough that someone might want to rip you off. Anything you draw is automatically copyrighted whether you put that stupid little notice or not. If someone wanted to use it without your permission they could easily erase that copyright message anyway.
If you actually want to include, I suggest making it a lot less obvious (the copyright notice has a bigger presense than the drawing itself!). You could use a thin brush and write it very small, or simply use the text tool and put it in the corner of the picture out of the way and not distracting.

I agree with Neko, the eye brows and hair tuffs look like they were glued on, not ther naturally.

I like the eyes n.n Very nice how it looks human, yet Cat like at the same time. The Shading Is superb, good job on the very defined Cheek bone, how you painted the colors is great to, I love it! n.n Saikyo!!

Outstanding work. Must have given a satisfied feeling when finished.

I did this kindda thing in my Color and Design art class... well.... you've got something just a bit off course on your "cone" because... if you wa-- oh nevermind.... -_-; *cannot explain it well enough* well.. it's good! just needs alittle shadow on the bottom or something... I guess... but... I LIKE IT!!!!

I know it sounds strange but I am really impressed with the eyelashes. You manages to make them so thin and fine that they look real...very nice job
