The art overall isn't bad, but seems a little unfinished. I agree with previous comments about the pips - they might look nicer filled in, and perhaps just a wee bit smaller. The indices should be completely uniform, rather than having the hand-drawn look to them - even if you want them to look hand-drawn, you want them identical from card to card; all the "K" indices on the Kings should look the same, all the "Q" indices the same on the Queens, etc., and all the suit pips identical.
I think the court art would look better without a dividing line between the top and bottom halves; I'd say either go full-body with one-way images or make a proper two-way design with the top half blended into the bottom half. I'd also go for color art there, to give it a more finished, visually-appealing look.
As much as I like a plainer Ace of Spades, most people (meaning most collectors) prefer something a little fancier, with the deck name, maker, etc. listed on the card.
Good luck to you.
