Yes, you are certainly talented... I think that you did well on the hair, but the anatomy and eyes could use a little more work, of course... The eyes are really only bothering my in a few pictures... Though the anatomy... I dont know, that part is just so important to me. as you can probably tell, I have no talent for criticism...)
Right now you are still in the stage of finding out which styles, media, and tools that you love to work with. And, with that in mind, there is so much amazing potential for you; especially your pencil shading and detail work these are hard to prefect but, once mastered, become beautiful tools to work with.
I like the points of your picture. I think u should try working on the faces a little more. If you want them to have sharp chins you can still have that while making them look realistic. Any way you did a pretty good job.
