Art - Really liked the whole set-up to this strip with the background, the detail on the tap and the bar itself. Panels 1 and 2 are basically the same, but with the story it is expected (not much big action going on). Also, Jase doesn't move a lot again, but the facial expressions are done well and help to serve the story.
The only real complaint is the coloring and placement of the shading, Robbie more so then Jase. The color seems too light and again the placement under the eye and on the chin is just weird. It looks more like he has eczema then that there is light coming from the right side of the panel.
Story - Simple set-up and a pun for a punchline. Nothing groundbreaking but it was enough for me to chuckle. After all between those two getting it RIGHT on the first try would have been more unlikely then the beer slushie (which does sound delicious).
