Your work is very good, and should not be a barrier to success. Your biggest problem is keywording. Take this image for example:
Your keywords are "coffe, cup, dinner, dish, meal, object, porcelain, tea, white". You have misspelt "coffee", and "dinner, meal, object, dish" aren't relevant to the image. My keywords would include "espresso, mug, saucer, ceramic, contemporary, modern, plain, empty, shadow, isolated".
... good luck!
