Inside my packaging

After finishing the exterior of my packaging I decided to look at the inside. 
One of my key pieces of information was that I liked using charcoal so I decided to work in this way, but I also felt my design needed some colour- so I looked at using chalk as well to make it more visually interesting (and to show that I don't just like black and white)

This is my original drawing:

I wanted it to look cartoon-ish so I drew it in a sketchy style not being too precious with the lines, but the colours didn't look very vibrant, so I edited this on photoshop, printed it and used it within my packaging.
