"HEART" challange

i just loved these weeks theme.a "heart" zt with our heart for little Artoo who has been so ill...and i loved to see healhing hearts flying to Canada along with your best thoughts.here's my late contribution.
used orbs + blind string to form a heart shape.
still will google about how to make a transparent orb and hopfully will learn how to pencil shade it correctly.i thought maybe someone of you would take charge and show me the way but i know it is too much what i'm asking.still if you have a good link for me please just write to me.thanks in advance :)

all the bests for all of you with my whole heart :)
