The introduction of the park set at night needs to fit in with the rest of the shots. Isolated I really like how the 'darken' blend mode picks up the original cool blue tones of the render and makes it feel like night through colour. However the rest of the shots are all only made up of tones of the background with the renders being colour burned into it.
I think with the all the solid black in he sky and shadows the colour burn mode is too harsh compared to the rest of the light pencil sketched look backgrounds and might be a bit jarring even though it will be introduced as a new environment as a new verse.
Again in isolation I think the experiment with the colour burned layer with a mid grey casting the sky a deep red bringing the tones out of the paper is really nice. The overlay of the render then burns in the shadows but highlights everything else so the contrast is massive. It does give a really nice feeling of night time being lit harshly and I may use this but it could still be a bit jarring.
I wanted to try and bring this more in line with the rest of the shots and knew using colour burn was the only way to get it looking the same but the blacks in the render were much too harsh.
I did a bit of colour correction on the toon render layer, pulling the Output black up on the levels to make the whole image much less contrasty and more mid grey. This gives the background effect of the overlayed version but gets rid of the over exposed highlights letting the paper show through as the lightest background element, allowing the subject to be the brightest object in the composition. I am happy with how this shot is looking now. I think it fits with the rest of the shots in terms of blending and transparency but has it's own unique look because of the rich night sky. I also like the slightly gritty noise at the edges where the vignette is blending with the cranked levels. This gives the night time shot a bit of reality as if the camera's iso is set high and making the dark areas more noisy.
