Why no-one's going to hire me as a professional Photoshopper anytime soon

Thought I'd jazz up a photo of me and Jess in the fancy Reims restaurant a bit. It was really hard though, mostly because the wall was the same colour as the (now wonky) table. I also forgot that one of the prime qualities of glass is that it's transparent. I now have a full-to-the brim martini-style glass instead of my wine glass and I just got rid of the water bottle altogether. I also got rid of the wine bucket, but seemingly digitally spilt its contents on the tablecloth in the process. On the bright side, I made my arm a bit skinnier!
