@Sami-K Haha cute animals! They look terrified. I like the colors you have chosen, and the lighting.
I do think there could be just a little more light on your characters though. I'm viewing this on a small tablet, and at this size the giraffe and elephant weren't immediately recognizable because their ears blended into the shadows and only their eyes and teeth popped out. So I'd maybe add some light to their ears so their shape is more readable.
