Hallo, I'm pretty new to painting things in photoshop.

It's literally just got flat tones and gradients in that image, so can be done with just about any opaque brush such as a hard round, and then a soft brush for the gradients. You can keep things on separate layers and use clipping masks to keep the shapes clean if you want. The image is pixelated to hell, but it looks like the background might have some slight texture to it, which can be achieved either through manually painting it in, glazing with a texture brush such as a chalk brush, or overlaying a scanned texture of something like watercolors.

You might want to consider using Krita which is very similar to photoshop (same layout, almost the slame hotkeys), is open source and great variety of natural feeling brushes.

However I don't think that brushes are your issue. That painting doesn't look like it would need a special brush to be painted as it has very clear lines with a bit of texture which you could fake by putting a paper texture layer on top with multiply by 20% or so.

>natural feeling brushes.

This is exactly my gripe with photoshop, none of the brushes feel natural. I will have to check Krita out then.

There's plenty of brushes that feel natural. Just look for something like Jaime Jones's brush set. You can also use the mixer brush to get a more natural look.
