In my opinion, the biggest hindrance I see is the fact that your cabinet style has that cathedral type arch on them. No matter what you do to those doors, they will not ever look 'modern'. Even tho it might be more expensive of an option, I'd suggest painting all of the cabinet boxes, and investing in brand new cabinet doors that have a more modern style/finish that you like.
The soffits aren't helping achieve a 'modern' look either but you have to draw the line somewhere right? Since the soffit will likely have to stay, why not consider adding more lighting to them to help bright the space. the small "gimbal' style recess lights would look great there and help pull it towards being more modern, with the added benefit of lots more light.
Good Luck,
