It's pretty good! Everyone's got their own style, and you certainly have your own! However, I think you should take a look at the right leg. See how it's bent? Now, I may be wrong (I couldn't see the whohle picture) but it seems to be bent at an odd angle. Here's just a little advice, one artist to another. When drawing (people especially) make sure it's realistic. As in, don't have an arm bending in the wrong direction, or a foot resting in an inhuman position. That leg seems to be bent out to the side, something that isn't possible for most humans.
Just something you may want to consider. ^_^ Other than that, it's a lovely drawing. I encourage you to keep going. Everyone gets better with practice!! smile
It's good! she looks a bit sqaushed the arm holding the cupcake is a little too thick and short and one leg is bent like a flamingo, if you know what I mean XD if you use a ruler when you draw the basic shapes and lines (the rough stage or whatever you may call it) you can make the limb length more accurate, extra long legs (or lara legs, as I call em lol) are okay though XD
who am I to give advice? I work digitally rather than traditionally (too much work if you ask me XD)
