I was practicing with coloring pencils :)
Done with IKEA coloring pencils (actually they're quite good for their price - 2 eur 50 cents for 10 pencils set ).
So if you wish to try out coloring pencils, but tight on a budget - it's the best option in my opinion (second best is Deli coloring pencils from Ali Express, which are rip-off from Faber Castell :) ).

Done in March 2021.
