This is a random assortment of drawings I have done in my time at MCA.
Lookin good! The rust texture is really nice and so far there's a pretty simple and effective color palette. I think the drawing could definitely benefit from more disrepair, though. Maybe some pieces have fallen off and are lying on the ground around the shuttle. Show some rivits popping out of place. If it's a shuttle graveyard it would be nice to see other shuttles in the distance. Possibly silhouettes. Show some faded markings. Maybe some animals living in it?
