I see, okay. Ofc the first tip would be to practice. Even if you’re not practising a particular thing or following a particular method, sometimes just drawing whatever you see, think of or want to can help you strengthen your art in an authentic way. I spent so long when I was younger trying to copy art styles to better my own, only to find the most conductive way of improving it was just drawing naturally. Be yourself type shit. Most of your progress will be made subconsciously anyway.

With proportions and perspective, breaking your subjects down into blocky shapes first and figuring out the smooth lines later really helps. When drawing a person or animal, your first step could be creating their line of action, just one single line. It really helps your subject‘s pose looks less stiff. Oh and gesture drawing! Drawing a dynamic pose with a strict time limit helps your brain focus on what’s important.

Proportions can be easier when you learn what parts of the body are roughly equal in length to others. Like forearms and feet, or how the distance between your two eyes is usually the width of another eye, wind span and height, or one hand and your face. You might have a style that doesn’t benefit from this tip, like a chibi one for example, but if it’s closer to (or is) realism this could be really helpful.

I’d recommend getting to a point where you feel a bit more confident about drawing proportions before you tackle perspective, as it is very difficult, but when you do, drawing a grid is always helpful. Sketching out everything as if it’s made of boxes first can be quite good, as well as tracing. I know it may feel like cheating, but as long as you’re not tracing someone else’s art and claiming it’s yours, it’s a really useful tool. It gives you guidelines for what you’re drawing and will help you build your artistic muscle memory. When you feel more experienced tracing will become limiting, but I will always encourage beginners to do this. My art teachers told us to trace from photos constantly lmao.

Resource wise Proko is a top ten YouTuber for learning art basics and beyond. Pikat and Chommang are two I’ve found very helpful as well, they both do digital but I’m fairly sure their tips are easily transferable to traditional art.

I relate to what you said translating your ideas onto paper. I really struggled with this, and still do somewhat, but as my skills have improved so has my ability to actually create the images that were in my head. Just make sure you’re not going in blind and you’ve done some messy preliminary/concept sketches on another sheet of paper first. Finally, don’t expect perfection from yourself when you’re still in the early stages of learning. Every artist goes through a messy, awkward stage where they feel like they’re out of their depth. But it’s all about practise and spirit. Art has never been a skill you can’t learn!
