Sweet Sunday Sketch Challenge and TGF CHA Relay - phew!

I was determined to complete a challenge this week and I've managed it! In fact, I'm submitting it for two challenges - the Sweet Sunday Sketch challenge #53 and TGF's CHA Relay challenge with their free digi, Mer Ian, who was fun to colour in! I thought the sketch was perfect with that big circle - thinking bubbles here! - and a mer-man! So here it is...

And the SSSC #53 sketch is...

I don't often use digi images and I found that the printer ink ran when I used my Copics. Any advice on what I can do to minimise this would be most welcome! Or should I just use colouring pencils or chalks?!!
