I love your use of line weight, Keely. The super thick outlines around the major elements, and the much thinner, more delicate lines around the details... and the bit of irregularity to the lines so it still feels very casual. The vertical composition and the white space around (with the visible texture of the canvas) as well as the many layers of foreground and background (and the... foliage... bushes... stuff, sticking out on either side and the ears interrupting the otherwise straight vertical rectangle) makes it quite interesting too. :D
I love your style of work, especially the ones done on scraps of paper--the first Boston Terrier is especially cute, it looks like it's looking through a window from,as Zaggytiddies said, "Keely doggie world". Have you done any paintings of Boxers?
eek! don't you just hate creative people, I always tell my sister that whenever we sees beautiful paintings in an art gallery. This is one of those time! A true artist with a style all their own!! Love your subject matter and the cheerful color combinations.
