I think your elevation is already done and what is left to be done is plastering and cladding. You could use wooden textured tiles and ACP sheets to clad the ceiling and walls. Use recessed lighting on a cool white tone for contrast.
Hello Manjunath, the scale of the building looks decent. You can do some interesting things on the facade like vertical gardens with louvered panels flanking on sides or you can even do innovative screens.
