learning how to create cool charms

HELLO.. i've just been teaching myself how to use polymer clay. i just made a few small items to begin,my first few were good,but i needed to get better,because i want to start selling them so i can go visit my birth family. i'm adopted and thought this would be a great cfart to start. which it is. i buy clay every two weeks.i'm now doing earrings,and doing a few cell phone charms. please feel free to comment on my charms.
