If you're referring to your photos....I'd suggest you take a critical look at your focusing and/or post processing. It's hard to say from the shoot with the model in your avatar.. they all look very low res and soft.
I think you should refrain from the on-camera fill flash. Try reflectors.
This shot looks like the model was pasted on the rock. I assume you used your on camera flash to light her. Light that comes from the camera angle has a tendency to flatten the subject. The back lighting in the landscape has a nice feel but you lose that feel with the model when you light her from the front. You go against the natural lighting. Thus making her look pasted in.
Way over flashed. She looks out of focus too.
Probably your best use of light.. but image looks soft..

Try some critical focus tests. Make sure it's not your camera. Night time shots can really mess with auto focus...
Overall the feel you seem to be going going for is fine..
but you have a ways to go with getting a handle on the technical side..
Keep it up tho...... the technical side is the easier part.
