Welcome to Gaia! ::

The only advice I can offer you is to keep studying up on anatomy and keep practicing.

And I don't think right now you'll have a problem with people stealing your artwork.

It is almost guranteed that your artwork won't
be stolen since drawing on notebook paper is
similar to adding watermarked lines on your art.
Otherwise, good effort and keep on drawing :]

^ Seconds that.

I was actually drawing at that level about two years ago... and I've only been drawing anime seriously for about three years. You'll get better for sure if you practice drawing and you copy poses from manga. ^-^ keep it up. Instead of sketchy-ing, I'd suggest you draw light, one-stroke lines and curves. You can go over one of those several times without erasing until you find just the right line. Then darken those lines very slightly and erase what's not needed. Once you get good at that, you should be able to complete the shape of a head in no more than seven to nine repetitions of the line-finding technique I talked about. Also, try to study the placement and shape of both various eyes and hair. Mostly, it'll just take practice.
