Happy Birthday

This was a sketch card basically.  I used Copic Markers on this little one from My Besties. The Happy Birthday is from Paper Smooches.  I also used a white Sharpie to make the shine spots on the balloons etc.
For the background I tore a post-it at the non sticky side and sponged Sky Blue Brilliance over the top to create clouds.  I used real string for the balloon strings but I think I should have used a color since they don't really show up in the picture.  Tell me what you think.
