I like what I'm seeing so far.
Now, read the rules CAREFULLY in regards to making your final submission. Because your deck has 100% unique faces, you'll need to submit art for ALL of those faces. I recommend that you combine cards into a single image for the purpose of display - for example, groupings of perhaps four to eight cards each - and provide images of all the cards, plus a few individual cards at full resolution as specified.
This isn't the submission, yet. I ask people to post here first so people can see your design and comment on them - after all, it's the members of this forum who will vote on the designs and choose a winner. It also allows you time to make sure you have everything correct before making your official entry on the topic in the Playing Card Plethora board, which I'm about to go and more clearly mark for people to know where to post.
In other words, make your mistakes here, because you won't get to correct them there.
Did I mention the part about reading the rules carefully?
One more thing - GOOD LUCK to you and the other entrants!
