I’m not too familiar with these characters and this series, but I understand André Franquin originally created a marsupilami character as part of his work on Spirou, then took the rights with him when he left, spinning them in to a new series of the same name. After his death, other creators worked on a new volume of series, such as Batem, as seen above. [Lambiek]
Note their incredibly long tails, which are like a super-powered fifth limb. I kind of wish I had one of those, as silly as it might look.
I´m embarrassed to tell you but the image I posted above is one image file that a one minute search brought up and I know nothing about making image compositions.
Oof, I tried searching for “online composition tools,” but they all seem to be meant for stitching together panorama photos to produce a larger panorama photo.
Finally I hit on searching for “online gallery image tool” which led me to this one. Good enough!
I tested it with random images. That´s definitely good enough for me. Thank you for the hint, might come in handy.
