Experimenting with Gouache for the poster

I made a small little mock up of what the final poster could look like...I think this is a lot more impactful and dramatic than my previous collages. You can not really see it here, but using gouache to paint the background in layers - one of blue, red and then black - adds a lot more texture and depth of colour. I also like the intensity of the yellow sunbeam against this background and the 'swishy' texture I put in the pale blue dot - mimicking the sky and clouds of earth. I also think the composition - the scale of the 'pale blue dot' and sunbeam, combined with the amount of negative space - is really effective in creating this sense/atmosphere of vastness and the insignificance of earth.
