I would look for ways to indicate light through your line work an example is the cymbals they would have a shadow between then and be darker towards the bottom. You can also have furry textures be heaver towards the shadow and disappear as they curve into the light.

I really like this so far but I would like to mention that when I squint at this the blue on the bear is very strong and brighter than the warmer light. I'm making this point only because I assume the warmer light is your key light? Nice work so far
@lucelfo You don't need an app, you just take a screen shot.

Almost time to work on the characters
@nessillustration I feel you are wrong about laptops not lasting. That is all I use will never go back to a desk top. My Sony Vaio is seven years old and runs just like I bought yesterday. I also have a Dell that is four old that is perfect. In the past my Dell studio was good for eight years before I gave it away (only because I wanted to upgrade)
@art-of-b I live in the West Kootenays but I run resort kitchens as a chef so my work takes me all over the province
Ha Ha I also live in the middle of nowhere British Columbia
@kristin-wauson When a small child hugs a large animal they spread theirs out very wide like they are trying to wrap around it. They also will turn their head sideways and press into the fur. You could have her feeding the bear a fish
very cute, off hand the first thing I would look at is the lack of shadows both form and cast, you don't need shadows for all styles but you introduced reflections in the water so you are already considering your light. The back are is a bit dark in value and may not really even be needed. I' not sure I would have the open mouth with seed teeth people will recognize the watermelon thing with out it and the seeds give teeth effect (this is a personal thing I try not to render out teeth in cartoonish work)
Cheers
My number one rule when I paint is to pick the ambient hue first and tone the entire canvas in that color and then base my unlit colors on this color choice before I consider my main light source
