One of the benefits of painting with acrylics is that further washes of colour do not disturb any previously dried paint. Unlike watercolours where if you add additional washes of colour you can loosen any existing underpainting.
This means that it is simple to change a snow scene into another season. However it does not work well for changing other seasonal painting into a snow scene. :-)
How to do this
This is a really easy technique. Apply washes of colour over your existing snow scene (the top painting is the original one). All the shading will still be visible and the white of the snow will change to the colour of the wash you are applying, as shown in the second picture
Increase the detail in the foreground
In a snow scene a lot of the vegetation is covered with snow so the amount of grassy things you will have in the foreground is reduced. However, when you change the season of the painting you can add a lot of grasses and plants to the foreground to enhance the picture. This will also add to the feeling of depth. A few extra grasses have been added to the third picture.
This is also a good chance to introduce more colour using flowers which will add to the change of season feel of the picture too. You can add as much foreground detail as you like.
