I usually use photoshop for most of my work but when it comes to traditionnal, I use watercolor inks : ecoline or colorex (colorex being my fave). If you live in united states it might be difficult to find them but you can try the dr Ph Martins instead. Colors are not as bright though.
It’s really important to find the paper on which you can work comfortably. I use the Lanaquarelle, satiné. It doesn’t drink too much, you can go back on it several times without shreding it and it is also very easy to draw and erase on it . It’s cotton based and acid free. But really you have to try a lot of paper before finding your own.
you can now register on my website to be sure there’s one for you. Sorry butt the Tumblr message system doesn’t keep track of the sent mails and I cannot be sure to remember it if I don’ have it written somewhere ^^
yes, you can ask for any character you like ^^
