Thanks, it was definitely in the hundreds, if not over a thousand, of hours of card design and artwork in there.
img width=188 height=288 - are the specifications for the sizing of the cards in the portfolio, it was rather arbitrary trial and error of numbers
as far as the dimensions of the card art itself, i used to know it by heart, but i had to look it up- its 256x256 typically i work on a larger scale in photoshop, ~2000x2000 with a resolution of 720, and then when its done i resize it to 256x256
