Hello. I am new to critiquing, so don't judge me for my thoughts. Anyway here's what I think:
general appearance: The picture isn't anything particularly new or original in concept or execution, though that doesn't particularly matter; it's a simple, short, and sweet picture
anatomy of character: the general anatomy could use some work. I would suggest using a reference for the character's specific body type to help. the anthro elements of the character seem to be spot-on
coloring and shading: the coloring for the background is rather nice. it uses more subtle colors and changes and seems to blend together rather well. the colors for the character, however, could use some work. the colors for the ears and flowers are rather extreme and don't look nice to the eyes.
Line art: the line art is the thing I dislike the most about this piece. it's well... it looks like it was drawn with the mouse. that's all I have to say on that matter.
that's enough of my ranting. goodbye.
