Hmmm, let's see...the carnival hairpin, snowflakes, new years pin, the big bang, yumeh ears and tail, chilly the polar bear, and bunnies...possibly some v day stuff to give away in a thread during the upcoming event.

As I stated earlier, you have quite a few things that I like and I'm willing to work for them.

Understandable. Pixels art tends to be harder to value because it so many styles, levels of detail, etc, and yet all falls under the header of pixel art. That and people tend not to know how to react to 'I spent x number of hours on this tiny thing, isn't it cute?' At any rate, I'll let you determine what you value them at as we go for the pixels, since I'll be working with different styles. Perhaps we could even work out a system where I just list some items I'm interested in at the time and you pay in whatever item(s) that you think that particular bit of pixel art is worth. That way I can feel out which styles you like best and such.
