Looking for critique, Im losing faith if photography is for me.

Someone want to critique me again? Im a horrible photographer and about to give up, i dont know if i have it in me. This $600 Sony NEX cam could very well be wasted powerful hardware in my hands cause my shots are looking just like reg P&S pics. Cant even tell its from DSLR like quality.
The landscape was shot in landscape and the sculptures in portrait.
