Any ideas for improvement?

The only improvement I could possibly point out as you seem to have a great defined style is to work on more dynamic poses so that the characters don't feel as stiff, like making it look like there is more weight in the elbows of the bathtub character and the feet of the pink one so that if feels like they are actually in the background you put them in or doing the pose you have them doing

Thank you already :) Can you tell me how I do that? Like putting more shadows?

Sorry was busy. There is a video "Bring weight to your figure drawings" on YouTube that really helps explain how to do that better than I can

The last one in particular looks amazing
Maybe like dynamic shading and animal head/face anatomy?
