Since I don't have a scanner I can't post my drawings but hopefully I'll have a way to post them sonner or later.
I had some time to work on this the other day but I couldn't render for the past 3 days so here is what I have till now.
I only worked on the right side so the left side looks horrid (that is why I choose this angle

).
I'm hopping to have some time to work on it some more this weekend.
All textures are temporary.
