well, as icepick said, nobody is pushed for time. you can still work on it if you'd like (which would be great if you can find the time for it). there is no deadline.
also, just as a nitpick, i'd probably move the top left spade and place it here if you don't want to overlap it with the nine. perhaps you can also shift the bottom right spade to the right a little if you want to keep some sense of symmetry going.
That looks very good; it gives me inspiration to continue mine (which will be done soon, I promise)...! The circle-bubbles around the edge look interesting, and fill in the empty spaces, without interfering with the card itself.
I find this to be quite a cute piece and I enjoy the circles around the card, they really help fill in the negative spaces. However I do have some issues with this card. First off, I feel that the diamond around the Oddish looks really rushed and I can see the line overlap on its leg. I also find it rather rushed due to opacity overlaps on the diamond, doesn't look clean or constant. I would keep it a solid color if I were you.
As for the whole piece, it looks like you merely used one layer (I can tell because of the shading overlaps). If you used multiple layers, it will reduce the chance of colors overlapping (you can use one layer for lineart, the coloring below it and so forth).
Finally, I find that the suite diamonds are out of shape. If you can, use the line tool over free hand, it will make your lines much cleaner (I'd recommend using it for the center diamond as well.
I imagine, for planning purposes, a beach scene, maybe near Cianwood; the holes where Shuckle sticks its limbs out of might become more heart-shaped. Quite possibly, one Shuckle will be eating a berry?
