I think poster colours are the best cheapest colours we can own to make very beautiful glossy paintings. I came to this conclusion so recently as I started trying to make more and more paintings with these.
Here I tried to recreate a beautiful landscape photo into a glossy painting with poster colours. Here is my painting.

Materials I used
Paper 200gsm
Poster colours
Brush
Pencil
Masking tape
Water
Art making process
Step.1 - Preparing the surface
First I wanted to fix the paper on a plane board. So I used paper taps which will also help to get clean edges for painting.
Step.2 - Painting process
Unlike we follows steps in making Watercolour paintings or oil painting here I didnt have any rules but one - Do fast. So I started applying the colors very fast from the top to bottom.

I was hopping that this will help me to keep my hands clean and I could avoid smudges over the painting part which happens often by mistake.
But here while using poster colours I didn't had a problem like that as it was drying so quickly. So first I started from top to bottom but then I painted wherever I needed as I knew it wont smudge.

The painting process was went with a layer by layer technique. There wasn't any restriction of applying colours like we should use white first and then dark as in watercolourpainting. I was able to try any colour over any other colour after the first layer dried.
Step.3
This is not an another step but in this final stage I was trying to fill the gaps in the painting process. i made some detailing in the bush. Drew sone more flowers, added shadows where it needed etc.
Finally
After I finished the painting, I removed all the tapes from it without damaging the paper.
