I disagree. I think it's perfectly fine to have a thread dedicated to your own artwork without any particular genre or classification. We naturally would like our art to be viewed in isolation, and if compared, only to others done by ourselves. Generalizing the thread out to everyone would degrade the focus and attention an artist cherishes in his audience. Also, I don't think classification benefits you, the artist, at all.
That being said, I'm glad to see another artist working towards a semi-traditional technique and perhaps in the future, mediums. If you are willing to commit, I can see potential in your dark and expressive figures and portraits. I recommend looking at Maya Kulenovic:

And I most certainly recommend using a traditional medium if you get the chance! I think, if you enjoy playing with portraits, faces, and lighting, you may find more versatility in oil painting. There are a few things that need to be learned concerning the proper use of the chemistry involved, but other than that I've found it liberating compared to drawing digitally.
