Both of them are so cute, little ms tree :D.
                     
I like the one that you drew at home more, but I also like the one you drew at the interview. Plus you drew a cute doggo to accompany the character <3.    
                       
And I hope they will call back on you soon and tell you that you get the job, because your art is really perfect to illustrate children's books ^_^.    
                       
Best of luck, my dear.
