The challenge looked too fun to not participate in.
Five postcards, all worksafe, mostly gen except for the slashy one. Image-heavy.
Disclaimer: the original pictures used are not mine. Neither are the brushes used (they were taken from Livejournal.) If credits are due, then message me and I'll be glad to give them.
If the images here are not clear, then follow the link on the bottom to view the gallery. Enjoy.
