I need to print the postcards to size and play with stocks more. It was also suggested that narrow down and filter out so I can focus on the outcome more.
They also answered my questions. After a discussion I found people favored the handmade designs, I've decided to use a combination of the hand draw and vectors and experiment with stocks more to produce the range in a hand made look. The group also helped with my layout queries and suggested i keep all text on the back of the post cards and keep the image as the main focus on the front. I need to play more with typefaces and pick one to apply to all.
