I like Pal's ideas. If you keep the tub, it'd be neat to try to undermount the sinks. I'd want to remove the tile on the window wall if possible because it looks institutional with so much dark tile. Ideally I'd just keep it on the floor and in the shower. My first impression is that it's a very long room, which the striped pattern of the floor tile accentuates. I'd break up that wall with taller vanities and a cabinet centered between them. Put a hamper or pull-out trash in the base cabinet. I'm not sure about white vanities since it's a guy bathroom and I don't think white wood is very guy-like. Maybe some type of light-colored natural wood. I would use a white quartz or Corian countertop. Hang the shower rod higher, and add some hand towel bars near the sinks.

Gorgeous rooms/colors! Personally, I would move the 'blue' paintings to the walls with the Silver drop gray colors. I think the contrast would make the room, and the arts, pop! Also, as someone mentioned above you can def. frame canvas (I'm an artist and do so regularly), and actually you can go to Michael's and pick up frames that would fit a canvas (without having to special order them). :))

Thank you for the color suggestions! All the walls in my house are the same light color and my living room has several different grays. Therefore, I'm trying to avoid gray, beige or white kitchen cabinets. There really is not much color overall in my house. I was trying to go bold but tasteful and semi contemporary with the kitchen. I'll really have to focus on the showrooms and colors I see in person as I continue with designers. Even though all the colors I see online look great I think they will just mislead me.

Your room looks very nice with the curtains removed. I would encourage you to leave it as is in regards to drapes. This is a more contemporary space and there is no need to guild the Lilly! The shutters are enough.
