Which Crop - GF Portrait

C&C are what i am after, so any that will help me improve my technique are most welcome! also why do all the images i take in v-low light situations with my 50mm 1.4 end up yellow/orange. is it because of the yellowish/orange of the light bulbs? theses shots were off the cuff, totally unplanned, with tripod.
