Not sure if anyone else has mentioned this but here's my two cents: As much as I like this concept as a whole, the striping pattern is a recolouring of the Penguins' current home/road set. Like I said, I do like it, but it would be kind of strange to see the Caps switch over to the Pens' template.
Good work though, great balance of colour. The only change I would make would be to change the colour of the sleeve striping so the portion by the cuff is red to match the hem.
