The $2 design is only one I like, BUT the one thing it's lacking seriously is some ripples on the water. It looks like an asymmetrical gap of laziness on the designer's part. The rest of the coins are ugly but I'll still collect one of each.
The 5 cents and 10 cents designs lack a cohesive border, like beads or leaves or scrolls. They look unfinished. The 25 cents is not bad in terms of "flow" but what is that bird supposed to be exactly? They could've put a Canada Goose on there. The loonie is a cluttered design and it took me a long time to figure out that there was a second train on the right, as it doesn't match the details of the train on the left. In fact, there's too much emptiness, no detail, on the trains and boat and lighthouse when compared to the bridge on the side with lots of detail, when the eye is naturally drawn to the middle where the action should take place.
In my artistic opinion, the mint ruined an opportunity.
