My reference pic:
My final work rendered in Eevee:
Although I struggled a lot on this project and I felt most of time like a child in a mist 
I 'm happy with the final outcome, especially with the light? Is it ok? What do you think?
Issues I had:
-
how to make seperate mesh in edit mode? Every time I add a new object it’s still one mesh in outliner. It made it difficult to select things and make a material after. What I did was to go to Mesh - Seperate (P shortcut) and then change for object mode and make material. Still not sure in which mode should I make material? SOmetimes had to delete twice materials to change them.
-
When selecting things and changing modes from object to edit had to hit Tab more than once to get what I wanted. I mean had to switch a few times between two modes and select things to select what I wanted.
-
in which mode can I use boolean modifyer? and how it affect render?
-
what about the light? can I change/add it in edit mode?couldn’t find it.
Can’t wait to find out all the answers
