Hello,
Today I made my first sale on GCU . I became very happy because I was thinking my cards are not good enough. Honestly I still have that feeling about my cards. I use my photographs to create cards and I am not sure people will like them.  

Congratulations on your first sale. I looked at your store and I doubt you should worry about getting future sales, you have some lovely cards. Just keep adding more cards, as with so few cards in your store, they will be difficult to find among so many.

Congratulations
 
I don't know why you would be worried about the cards they are beautifully done
some lack a few keywords but that is all, sometimes it takes a while to be noticed,
but now you have, the ball should start rolling and with such lovely cards they should
do very well for you, adore the yellow flowers with santa hats
 
Congratulation Hugs
