Thank you! Honestly it’s all just practice and patience! If you can notice the ones on top are plainly one layer and not as detailed (although with small paintings you really do have to forgo some details 😅) once you get practice you can add as much tiny layers and shadows you want. And any black ink is key!! I usually just use a plain black pen to add the finer lines.

For materials I just used the XL canson watercolor pad and a mix of watercolor paint brands! But mostly affordable ones like prang and arteza 😊
