cool ideas chromaTinker
the one with gravyard is pretty solid, now when you have idea of objects restoring life, I'd recommend you to go for thumbs exploration
different perspective and design, also do some reference gathering, it can help a lot .
still too loose to say something about most of them, the left bottom one looks interesting, like rising ship or city, the one on the right is too gereric, don't see any restoration happening, keep working, do some research, go for adequate line drawing
waiting to see more from both of you!
and here's mine
going for some sci-fi interior where group of spacetravelers will be exploring abandoned alien tomb
first was idea in my head, than I made so called moodboard (at the bottom) than I did a sketch (on paper, and digitally) using big blocks trying to get more solid idea of what to paint
after a while I decided to look for more ideas, so I made some abstract thumbs using my photo library and photoshop blending modes
the next step is to extract interesting shapes and design and apply it to line drawing above, will see how will it ends :)
