The cards look a bit under-developed. For TCGs it is necessary that each card is easily distinguishable from the others, and I feel like your use of soft lines, and a more blurred art style may eventually cause problems down the line. What I would do at this point is work on iterating through a bunch of ideas. Try to always make a better card and keep doing this until you have a huge portfolio. Try to do a card a day or something. Once you have a solid style and direction then I'd search for a programmer or designer.
