Am I good enough at photography to consider becoming a professional?

I started off with a Fujifilm bridge camera when I was 13, and I think my photos back then were pretty decent.
Now I'm 16 and armed with a Nikon D3200.
I seemed to have arrived at some crossroads. Should I become a pro photographer? Or should I keep it as a hobby?
I took a photography course, so I'm very familiar with the technical aspects of my camera, and please be aware I use MANUAL mode.
I would like to specialize in Nature photography and I'm considering War photography, despite the fact you'll all say I'm not thinking straight.
I do not use filters, I simply edit my photos.

All criticism is well received!
