I have had a look at your deck. Unfortunately, I'm not a great fan of art decks, which I think this is. Nevertheless, I can offer some suggestions:
I would like to see some more of your art up close, because I think you are rather talented, but in the tiny images the faces becomes a grey, undefined blob to me.
To me it seems rather unpractical to have the number and the pip in different corners.
Some of the courts seem a bit unfinished to me, like if they are preliminary sketches, that holds the promise of something truly magnificent, but it's not there just yet.
What does the number cards look like?
Best regards and good luck
