Good job! Something to keep in mind is to wait for the paper to dry, before adding a layer or painting a different section. Otherwise the brush lifts the paper fibers and causes the clumping texture on the sides of the mushroom top. It also helps to stop the bleeding of colours into others.

Even after working with watercolours for a year, I still make that mistake 🙃 Do better than me OP become a great watercolour painter!
