art req-Brianna and Chase

Characters belong to Techley 
Art by me Noe-Sensei 

I enjoyed working on this request, I loved these two, they are so cute , I struggled with the guy's arm placement, I still feel that it looks odd, but anyway I liked how the overall drawing turned out  ! I wonder are they a couple, or siblings 
Thank you very much.
I used a free background from pixiv.
