You did not provide a source for the art for the curator to verify whether it's copyrighted or open-source (and if the artist has requested permission before use, you should say somewhere that you have received permission). Alternatively, you can use a stock image, for example
http://www.sxc.hu/photo/1256359 (remember to include the source in the "Art" section of the table).
Now, formatting. You should change the forward slash character "/" in the topic title (edit the topic in your opening post) to a pipe character "|". I would move your opener/introcution into the "Notes" section of the table. Finally, the un-upgraded card, in both the card image and table, seems to have an extra space in its name "Lop-Sided Dice".
Everything else looks good.
