- Fundamentals: lines, circles, perspective, color theory. Fundamentals are important to practice, regardless of your skill level or area of focus. Draw A Box has in-depth lessons from basic lines to complex organic or mechanical shapes. This kind of practice is possibly the least interesting, especially in basic levels, but it's super valuable. If you are between projects, and don't know what to draw, spend some time in this area.
- Drawing from Life. You can draw from photos, too, and that might even be easier, since you don't have to translate from 3D into 2D. But you'll get better practice drawing from real life. That ability to translate between dimensions is really useful. More than that, though, life has movement, depth, and a certain intangible 'realness' that photos can't seem to capture.
- Copying someone elses art. The purpose of this is to study how they do it - try and see what the original artist saw. Best not to pass of those copies as your original art, though. Don't just trace - rather study the shapes, composition, and colour to really break down what they did and why.
- Iterative Drawing. Take a look at this video for an overview. But basically, try to draw a thing from memory. Then look at what you drew, think about what's wrong with it, and try drawing it again better. This method lets you deconstruct your own bad habits and really think about how things look. Training yourself to figure out what something looks like when you aren't looking at it really helps when you want to draw something you can't get a reference for.
- More fast drawings.While it's fun to get into the details of a drawing, your skills will greatly benefit from
drawing a lot of pictures quickly. You often get 80% of your learning from the first 20% of the drawing. You'll
have far better flow, energy, expression, and composition if you draw a ton of pictures quickly, than if you just spend
a lot of time on a handful of pictures. Then, when you pick your favourite on to add details to, your final
piece will be much more compelling.
Timed drawings can be especially useful - you learn to see the main shapes more quickly and more accurately. You can do a bunch of quick sketches, then later choose your favourite to complete - you'll be amazed at how you improve. Sites like Quick Poses and Line of Action offer some solid references you can use for practice. Hands, figures, faces, and animals - all great topics to study and practice.
- Study something from different angles. You can get a better feel for the space that an object or person occupies by seeing it from different angles. This will help your art develop a sense of depth that the viewer can really feel.
- Study something in repetition. Draw the same thing over and over. Divide a page up and draw the same thing in each section. You'll see the improvements as you go.
- Participate in Drawing Challenges. Stretch your imagination by drawing things that are outside your comfort zone. Maybe you're really good at drawing horses, but there are a lot of things you avoid. This is a good chance to notice what those things are, and address them. You don't want to be making decisions about what to draw based on your skills - it limits your freedom, and it shows when an artist goes out of their way to avoid drawing something. Do all your figures have their hands behind their back? Do all your faces basically look the same? Do you have a lot of characters all just floating on a plain background? Try to break your bad habits by stepping out of your comfort zone once in a while.
- Follow some tutorials. Talk to other artists about their process. There's no need to re-invent the wheel. Many artists have come before you, and they've learned all sorts of neat tricks. These How-To-Think Tutorials by the Etherington Brothers are a great resource.
- Draw Every Day - even if you only have 10 minutes most days, spend those 10 minutes. You'll gain much more from 10 minutes a day than 70 minutes in one chunk. If you can spend more than 10 minutes, even better. Just make sure you draw something every day.
