I know very little about Lithuania. I think it is a long way and a culture apart from California, USA. With that in mind:
Here there's a big difference between boy (blue, never pink; automation, never flowers) and girl (pink, flowers). What's it like there?
What fabrics are available to you?
The pattern you've chosen is great and looks like you're doing a great job.
What is the child's favorite things to play with? Often this can be a start for fabric choices.
Here toddler quilts can be anything from pretty lights (pastels) to happy brights to high contrast strong.
I'm not a fan of brown, but it can be OK. With the prints, I might like medium-dark torquoise/teal/blue-green (this is a language thing-not sure what the color would be called there).
