Rest of my cards on Etsy and DeeCon mascot design

So first of all I've now got the rest of my cards on Etsy: 8 different artworks and the original lino prints for Flower Elf.
You can find them all here: www.etsy.com/uk/shop/FallenFan…
I've also lowered the price from £3 to £2.50, still with free postage.

These are all the artworks I'm selling as A6 cards:
   
   
 

I've also taken those cards down off of Redbubble since I was selling them for the same price there but not making near as much money from them. However I do have some different cards on there as well, and some alternative versions of the ones on Etsy: www.redbubble.com/people/night…

So here's the front on sketch of my Elven bard to enter the DeeCon mascot competition...If I win I'll get a free table to sell at which will be really good. 

To be honest she's not the most creative of designs, I'm hoping there's enough about her that they'll like though. I've actually added a bit too much detail in her, it's really hard to find a colour palette that some bit if detail or another doesn't get lost in since we can only use four certain colours. 

Here's some of the colour combinations I was thinking of...I'm not quite happy enough with any of them. I think I'll play around with what arias should be light and dark instead. For example, the first and second one are just colour flipped versions of each dress but the 4th one has different arias in different colours around the shoulders. Maybe if I can pick between what arias should be the same colour as each other first it will help me decided what actual colours each aria should be.
