Modeling a lantern (need help)

I’ve modeled the basic shape of my lantern but now i need some help. First question is, where would i find textures to fit the lantern in the picture for my model. Second is, the little bit that’s shown in red on the top of the lantern, how would i go about modeling that and placing it on my lantern? same for the bottom bit also drawn in red. Thanks for any help :)!

Reference image

1- sculpting you ornement
that would give best close shot but takes time

2 - try to take image of it and make a normal or bump map in Gimp may be or other soft
and use it as normal /bump image
but it wont show well if for close shot

3 - you could also draw the shape with skin modifier

happy bl
