Welcome to Gaia! ::

first drawing of the fox boy with the tongue sticking out
its by the left side, where a pocket for the pants might be
that brown thingy, i can't tell if its a pocket sticking out, or a glove, or hand, or what nots

i would probably just add in the other arm to be visible so it just seems a bit more balanced

only thing i can say are visual problems with the middle one
i know that the leg is suppose to be up as if she were taking a step
but for some reason it looks like she is missing a leg all together...

but of the three, i would have to say matter of opinion
i like the crisp shadows colors of the hair, dress, etc. for the first two
but don't like the blurry ink lines for the first one
and the cheeks for the last one works for that drawing but i don't think it'll work standing alone without the flowers and pink outline

and for the last one its hard to say
since its a chibi animal you can do whatever you want really to it
so it looks fine to me
maybe the front left leg, where it connects to the shoulder looks a bit awkward but besides that it seems fine
