Cricket and chimney flashing

See image.... Is this the best way to handle a cricket/chimney? It's on a 2/12 pitch with using a abc metals sl-16 standing seam panels in the northeast. I thought the counter flashing was best to be cut into the chimney, not face nailed? Also the valleys are very crudely cut and held with a few screws and butyl tape? The gaps are from 1/4" to 1/2" wide. Won't snow and ice open up these ares?

Well, this appears 5 months too late, but it really depends on the snow load. The more snow you have in this area, the more leak issues you'll have to deal with in the future as the butyl tape dries out. Ever consider polyurethane caulk? In snow country-- I live in Western Nevada, just off Lake Tahoe-- we solder our joints (yours looks painted, so that's not possible here), and we then use a Bituthene roofing material/"paper", on the backside of the cricket to ensure there are no leaks. Also, out here we do larger overlaps because water has a tendency to travel uphill due to capillary action once it starts going through the melt-freeze process. I've heard stories of water working it's way upwards of 30 feet, up a 6/12 roof. Needless to say-- I was floored.
