@ Derpy I'll do my best. I'll be using markers, so not sure how good they'll do on tinted colours. 
@Kiltman On it. Again, markers and pastels are not the best combination, but I'll see what can be done. Or perhaps I'll just use pencils... *scratches chin*

Okay, the current queue is: 
1) Silver Carrot's Skywhistle;
2) Derpestein's Tipsy Joker;
3) BlazingxLynx's Swift Star;
4) KiltmanBagz's Belly Laugh.

I'll update it as the work progresses :)
