about the hand, dont forget that some fingers are longer than others. also, before you're completely confident in hand drawing, try drawing it in different poses and gestures. Hands one of the most difficult things to draw.

Here I am again too shoot down all your preeety hopes and dreams! and cus i have to life...um anyways in my short little fashion, ahem:
the "foot", the leg would probably be thicker near the top and not at the bottom, Hand: the three fingers longer, and you dont have to actually draw out all the lines, the head, ha, head...thought it was a rabbit at first, the mouth probably wouldn't be so straight. and the nose has these hole like things in it so you might wanna try that, Soup, you could draw two curved lines for the word space so it looks like its curved and more like a cylinder, it probably wouldn't be so pointy either, the katana sheath would be straighter probably, where the handle is i mean, well thats a lot so ill stop, yeah and i don't draw stars sooo, yeah. is that the moon? wait, night, moon, makes sense,oh and if you wanna me stop say so and i shall, ill just go to christian's we'll be depressed together, k? k. oh, last thing, the ears should be more symmetrical and probably wider depending on what animal it is.
