Having trouble coming up with something to draw? No worries - while you'll eventually learn how to start from a tiny seed of a thought and gradually nurture it into a complex concept to explore through design and illustration, it's perfectly fine not to be there just yet.
For now though, here's an idea that might interest you.
Imagine you're far in the future when space travel has become a part of the everyday. Technology has advanced, and we've made contact with other intelligent life forms. Much as the internet made the Earth a smaller place, our universe too has become more... neighbourly.
Humanity's introduction to all of these different cultures has lead to many great things - not least of all the creation of many new tasty treats. But you know what aliens can't do? For all their technology and their conquest, they're awful when it comes to marketing.
Come up with a branded snack that you'd find on your space voyage. The possibilities are endless and can be as grounded or as fantastical as you'd like. From the realistic and admittedly sad paste we space-faring apes eat today, to the wacky nonsense designed to snare tomorrow's youth. Or perhaps you'll an entirely different route - tasty goodies with a cosmic horror filling!
This is another one of those things that aren't sold through Amazon, so I don't get a commission on it - but it's just too good to leave out. PureRef is a fantastic piece of software that is both Windows and Mac compatible. It's used for collecting reference and compiling them into a moodboard. You can move them around freely, have them automatically arranged, zoom in/out and even scale/flip/rotate images as you please. If needed, you can also add little text notes.
When starting on a project, I'll often open it up and start dragging reference images off the internet onto the board. When I'm done, I'll save out a '.pur' file, which embeds all the images. They can get pretty big, but are way more convenient than hauling around folders full of separate images.
Did I mention you can get it for free? The developer allows you to pay whatever amount you want for it. They recommend $5, but they'll allow you to take it for nothing. Really though, with software this versatile and polished, you really should throw them a few bucks if you pick it up. It's more than worth it.
