I've been working on this for a couple of weeks - an A3 sized fanart of the five protagonists of the original five books of the series.
Tsunami the SeaWing, Clay the MudWing, Glory the RainWing, Starflight the NightWing, and Sunny the Sand/NightWing hybrid. Well, my artistic interpretation of them anyway. I may/may not have got their colours and size differences correct, but I like how they look over all.

I'll try and rescan this at somepoint/get new scanner; my scanner was messing with tones whilst scanning three sections of the art (I have an A4 scanner) and has subsequently left vertical lines on the merged image.

Coloured with: watercolour paint base, Polychromo pencils, assorted markers, and gel pen.
