You might find the plant looks a little less funky if you stop cutting off the dead tips and just let the leaves hang there until they dry up and detach easily from the base. At least that's what I do. The dead tips are part of the natural appearance of the plant. The more light, the better indoors, as others have suggested. Right in front of your sunniest southerly facing window would be ideal (assuming you're in the northern hemisphere). The plant is also pretty huge for the size of the pot, but it probably would be best to wait until spring to make any changes there.
