Hi, I am very new to the world of Digital Imaging. I am currently studying a Photographic Diploma part time and require some feedback, good/bad or ugly regarding some images produced for assessment to indicate a basic grasp of photoshop and how it can be used to create works. All photos used (apart from one background) have been taken by me. I would love to hear what the more experienced out there think and how I can improve my skills. 

Thanks in advance, any comments greatly appreciated.
