I made a miserable attempt with my Vehicle project at Christmas, so it was good that it was needed to be finish.
Here are my thumbnails that I did using felt pens, just random scribbles and ideas out of my imagination.
A quick concept and learning different approaches from the silhouette
Here are line sketches of different concepts moving lift, flying vehicle I was thinking. I'd then paint over in a Sci-fi look. I do feel I could added some textures to them but might be a bit much.
Here is a quick blueprint design in pencil. Trying to understand perspective and design
Here is a paintover from the blueprint design I quite like the look of it at the moment. I might improve the final with texture brushes and colour.
Here some better render of the Jet concept. I wanted to see different variation in colour and texture and I was trying to improve in my design presentation as well.
