So I've decided to paint that picture, this is the steps I've taken so far.

I drew my template on a canvas

Then I drew the character details

Now I'm pretty sure drawing was the easy part.

Then this morning I started to paint the background.

I'm leaving it now because painting the characters will harder, and I'll do that later.
Any painters out there that can give me some advice please. This is honestly my first time painting, and I'm worried.
