Drawabox - For absolute beginners and masters alike. It is very rigorous though but it should help you lots on the basic foundations of drawing.
Ctrl+Paint - Another useful website for beginners. Contains lotso tutorials that should be easy to follow.
Proko - The quintessential resource for beginners. It should get you started with the several fundamentals of art. Don't take too many at once tho and start small.
ModernDayJames - Has a lot of useful videos for anatomy.
Marc Brunet - Yet another artist who has a lot of useful vids for artists.
If you still doubt yourself or you're still trying to get over that one big hurdle, here's a couple of vids to get you started:
How to Learn Pretty Much Anything
Why You should Start Drawing
A Beginner's Guide to Drawing
They're relatively old videos but they're still relevant to this day. Go give em a watch.
And finally, try to read several of Andrew Loomis and George Bridgman's books. Especially Andrew Loomis'
Figure Drawing for All It's Worth and George Bridgman's
Constructive Anatomy. They're quite a mouthful so take it slow. Or read art books in general. There should be lots out there.
There's also this personal philosophy of mine that might also help. You can learn by
imitation. After all, that's how we've learned all that we need to know in this day and age. You can start by looking at paintings, illustrations, and artwork from artists you like and try to break them down into individual pieces and steps. Breaking down artwork is not an easy task but it does provide insights into what techniques they have used and what fundamental concepts are illustrated in their artworks. After that, you can try to reconstruct them. Then you can learn some more by exploring those fundamental concepts and bolster your foundation.
Don't trace artwork though, copy it 1:1, and claim it as your own. Using references is actually fine and highly recommended especially if you don't know how things should look like on paper or canvas.
Now, it's quite hypocritical of me to say all this especially when I haven't been following through for quite some time. But I hope they help. Cheers mate and happy drawing!
