Immaculate Concept is Steve Peace's shop in Calgary, AB. Steve puts on the Calgary and Edmonton tattoo conventions. He's a really experienced tattooist and been around the block, well-rounded, very nice guy. I think Immaculate is one of the bigger shops in Calgary. The Munk artist you've linked though is definately not my style of tattoo, so I don't have comments.
I don't know much about Calgary's tattoo scene...I'm from Edmonton, so anything Calgary related I am obligated to yell "Flames Suck" and take a cheap shot at their city lol (jokes, Calgary's a nice place). Lots of world-class tattoo makers in Alberta though, these would be my first choices if I were going for a full meal deal leg piece:
Calgary - Scott Veldhoen, Rick Wilson
Red Deer - Lucas Ford & Classic Tattoo
Canmore - OllieXXX
Edmonton - Champion (Shawn Hedley, Rich), Lucky Strike (Scott, Brent), Doing (Seve), Showdown.
do your research, talk to local people with tattoos that pop about where they got em, go check out the shops in person. Everyone is pretty friendly in this area. Good luck. PM me if you need more specific recommendations for Edmonton
