I like the atmosphere of the piece. I'm rather envious of you, I could never use watercolour sensibly. Or, for that matter, any kind of paint. You handled the background well, the small details are amazing. I only have one little thing I dislike in this, and that should be the pug's hand holding the cigar. For me, it seems a bit too feminine. For a male pug, I'd have imagined something more sturdy.
Either way, I admire the picture. You can almost feel the laziness of a warm afternoon while looking at it.
