Your avatar image is pretty hard to 'read' in thumbnail size. The first impression is that it's a landscape shot. Not good if you are trying to attract models. They'll figure you are only interested in landscapes, not them and not bother looking at your portfolio.
I started out as an art major in college. Later, I became a member of the San Diego Photo Naturalists Club over 20 years ago. They were very strict about using filters, or seeing ANYTHING man made in an image. They also had regularly scheduled competitions, where a professional critique person would choose "the image of the evening", and "accept", or "reject" every image submitted. It was very educational, and good discipline, but, I felt the medium was stifling. I have since embraced Photoshop, and other subject matter, but the landscape stuck with me - and it is still one of my favorite objects of photography, (sometimes I throw a model into the mix for fun and variety).
Two subjective elements of an image - it's visual impact, and it's beauty, are my only objectives. The subject matter can be very secondary.
The whole point is, to satisfy your own artistic nature, and forget anyone else's ideas of "good subject matter". Before I became a member, a guy from The Photo Naturalists Club told me, at an orchid show, "you seem to be on the right track" !
Whatever you decide to do, do it because it is what YOU like to do, and because it satisfies YOU, even if nobody else agrees with your decision.

I really like your avatar pic. That was a great capture. You're other photos could use a little work. I think the one of the couple might have had more impact if the photo was a bit closer. I wouldn't mind seeing your nature work sometime. I shoot people on occasion, but most of the photography I do is of nature and also things I just come across.
