Some of आप may know that I post my drawings here, but I'm running out of ideas anyone want to suggest anything? I will also mention your name if I get around to doing your suggestion :)

आप could draw scenes from the tv shows. Like this one from Operation Cooties.

Maybe आप can draw a group of POM character with your OC that dressed with different national costume...

For example आप can draw Hans with Danish traditional uniform (if there's any, but i don't know yet), Private with British royal Uniform, Skipper with America flagged T-Shirt या even King Julien with Madagascar costume (Like in Movie)...

I have an example with OC costume >>
And here is Sergeant (Cpt. Taylor) With Danish Infantry Uniform (Actually Fidelis Uniform)

hmm.... maybe आप can draw Blowhole...but with an added twist. draw him as Flippy

Could आप try to draw my OC, Palm? Here's my drawing of her: link
If आप don't think आप can do it, it's fine.
Maybe try to creatate a charactor doing something no one would ever think of them doing! (example: Skipper watching Lunicorns)

first of all, are आप able to draw humans?

try drawing them one या all of the penguins with a special background. i've done that recently. here's an example

I was thinking maybe a Doris and Kowalski pairing pic,don't know if you've already done one.
