Todays concepts come from Jared Lammi. Jared has been making some progress with his concepts and I hope he keeps on striving to become better. The first concept is of both the Penguins and Flyers. I don't know if Jared intended to have both teams play each other in these jerseys but if so, it would be hard to differentiate teammate from opponent since both jerseys are gray.
His second concept is for the Vancouver Canucks, in which he has given them a Sonic themed jersey.
The one bit of advice I would give to you now Jared is that I have seen in most of your concepts you just fill in the areas with different colours and thats it. It would help if you tried to create striping schemes for the jersey to be more creative.
