I'm not sure exactly what you're asking, but I'll give you some thoughts since I had a mudroom very similar. The most used spaces are likely the washer/dryer area and the bench area, which is also the walkway to the garage. Your towers on the sides of the bench stick out into the walkway. I would also want the sink further from the washer/dryer so you have more clear countertop space. Consider including an area for hanging damp clothes, or at least a pull down drying rack.

If you stick with your current plan, I would move the pantry to the window wall corner , and then use the empty space in the corner by the door for the dog bed. Next to the bench, you could save money by using open shelves and hooks instead of cabinets. That was more useful for my kid's sports paraphernalia and shoes, for air flow.
