#1. Nothing really interesting about it. Decent sky color, but the building is underexposed...That's a hard one to figure out for beginners is balancing exposure between subjects and sky.
#2. Nice concept, just to much shadow on her. Natural light through windows can produce great shots, you just need your subject to be in the light.
#3. It's alright for what it is...just doesn't hold my attention subject wise.
#4. Best one of the series IMO. I like the conversion.
#5. This is a common attempt. Don't like the fact that I can see you in the reflection. I would try to find a unique item for the reflection, and crop it tight to the glasses to avoid the distractions of the carvings and all in the surface.
Keep practicing. And let us see what you come up with.
