Adventure Time_Finn & Jake (WIP)

So I have been working on my little Adventure Time cross stitch for the past couple days.  I finished all of Finn the Human, including the whites.  I also finished the black outline for Jake, and then I started to fill him in, but I did not like the color I had chosen for him.  So I undid it, and found another color which looks great, but I don't have a lot of it, and I'm nervous that it won't be enough... Here it is:

Finn is supposed to have missing teeth, since he gnaws things and fights monsters all the time, but I really didn't like how unclear he looked, so I decided to add some back-stitching to his mouth and teeth to make it look clearer:

I think it looks much better with the back-stitching!  Now I need to finish filling out Jake and then write "MATHEMATICAL!" above.  Here are some close-up details of before and after the back-stitching:
