Timeline Paintings

My brother in law, an architect, recently commissioned me to do some paintings for my sister, who does interiors, to put on a wall they've had some trouble with.  He picked up an idea from an art exhibit where each piece was hung flush with the next along the horizon line.  So we decided to take that idea and do a timeline of sorts, moments in their lives.
I settled on ten images, most are prettty small.  I took some photos of the process along the way...

And here they are, cropped in next to each other, just so we can see what they look like next to each other.  The sizes aren't comparatively correct though...

This was a fun project, as I really only do portraits and figure work.   So all of the architecture, landscape, interiors, etc., was all new territory for me.  Also, the palette was very limited (white, black, yellow ochre, and burnt sienna), when I typically use a lot of color.  The black became my blue, mixing with yellow ochre for the green.  And the burnt sienna became my red.
Thanks for the opportunity, Sam and Tris!  It was really fun!
