I did a search for Safari Quilt and came up with this site, thought I'd post the link just for another idea.

Not sure how huge those lions actually are, but it might be a good idea to cut them apart & piece them into some blocks or just even other larger pieces of coordinating fabrics? Just my thoughts, they look a little intimidating both of them coming straight at you like that, I think I'd try & soften them maybe with a little applique on the edges or something?
