I need so much help designing this space. It’s such an odd shape & it’s an open floor plan.

My goal is to create a space that is colorful & unique that flows well together. I need advice on how to create a dining area that can work well despite the big opening at the front door as well as a cozy family room that incorporates a tv. In the living room I run into the problem of the deck door and baseboard heaters. I’d like to start fresh on furniture, rugs & door curtains. Can anyone help me design a colorful space?

Pictures of examples are much appreciated as I’m a very visual person & I’m totally design stupid.
