Blue whale in galaxy :)

Hi everyone ^^
These are my first watercolor studies. I have no education on the drawing but I watched some tutorials on youtube and decided to make these for my sister on her birthday. After researched which materials I should use I bought Canson watercolor papers and Talens Van Gogh watercolor pallet. I tried my best but after that, I decided to improve myself in the drawing. I hope you like them and I'd appreciate if you'd like to suggest something to me about painting.
