In high humidity, I suspect fungus but it could easily also be some kind of sucking insect. Try swabbing the plant, especially the underside of the leaves, with methylated spirits. Also spray with fungicide. By the way, don't want to say this, but in the West the word 'swastika' doesn't have good connotations. I know the meaning is totally different in the east, but using that as your avatar name might not encourage people to help.

I would suggest using money plant (even picture above has it on top shelf) also spider plant is a good idea. these plants will add beauty also for air freshening.

Depends on what effect overall you want -- hot tropical feel (oranges and reds) or a bit more toned down? You can take inspiration from pictures of gardens with lime green heuchera or sweet potato -- often paired with chocolatey purple, silvery greens and blues.

Hi Nadia, Using different design styles for interiors has two consequences - 1] You may end up with a poor patchwork reminiscent of a interior design showroom. 2] You may end up with a perfect blend of eclecticism. Avoid giving each room a different look as this will not only break the continuity of the space but will be visually overwhelming. Instead try to blend. This way you will maintain a visual connectivity of different spaces and the entire home would look balanced and cohesive even on being eclectic. You may achieve this by using the following tips: 1] Use a colour palette that suits the theme. You may use neutrals all the way and splash a bit of colour in on a wall or two just to highlight. These walls may be the ones in your foyer or passage or balcony or simply behind the sofa or TV unit etc. Remember that the colour is being used as a highlighter so place it judiciously. 2] Each design style comes with a set structure and rules hence, use an interpretation of design styles and not the styles as they are. This will allow you to make decisions flexibly as there will be lesser restraint. 3] Have a clear control on the aesthetic. Minimize, dont overdo, else the space will look like a museum and not a home. 4] Make judicious use of furniture. Use colonial designs for all your loose furniture like chairs, end tables etc. Keep your beds and sofas clean and contemporary. Add eclectic cushions. 5] Use furnishings wisely - american pleat curtains in pastel hues, damask/textured wallpapers, natural fabrics like linen, silk etc for upholstery. Add a bit of greenery in the form of plants. 6] Use natural stones for flooring (rustic tiles would also do) with motif tiles to highlight spaces like the kitchen, bathroom wall or foyer floor.
