During long time of my work on ZX Spectrum I create some graphics too. Often I layed out loading screens which I didn't like, or add ones to games without loading screens.
First I layed out screens from games Chess and Planetoids by Psion. Unfortunately my versions of screens remains only on cassettes which I don't have. Maybe one day I make some sketch for your visualization.
Next was screen for game Dictator which was without loading screen.
Follows Infernal Combustion. Schoolmate of my friend drew the Dragon. I just redrew it in Art studio and add background. You must appreciate that original screen was not up to much.
Amazing game like Rescue deserved something better as you could see during loading. If cosmic ship on the screen remind of something to you, so let know that I took it from game Uridium and layed out.
T.S.S. liked my pictures so he asked me for loading screen for his game Mind crosswar.
I drew also loading screen for T.S.S.'s game Invertor.
