Well, thank you! Watercolour is pretty tricky, to be honest. I spent many years just drawing, then painting with oils, and now watercolouring. Having a good teacher really helps, because there are a lot of little tricks and aspects of watercolour you can only get to grips with by either spending a heap of time trying things out or learning from someone who knows already! The next thing is to buy the absolute best materials you can afford. Yes, I do mean the paper that costs $10 a sheet (you want cold-press 100% cotton rag), and the paints that are $15 for a 5ml tube. Believe me when I say the quality stuff makes a huge difference - cheap paper and poor quality paints simply will not move, blend and soak into the paper with the divine grace that good quality will. There is literally no point learning with cheap materials. I had a look at your gallery and I think your drawing is coming along well. I'd recommend getting a scanner, though (I work at quarter-sheet size, which is just under A3 and I've been using a cheap A4 printer/scanner combo for years that cost me less than $100, scanning half the page at a time and photoshopping them together) because photos will never be properly clean and crisp and therefore your art won't show its full potential. This is particularly important when you watercolour - a photo will just never show all that lovely subtlety and nuance that a scan will. Keep practicing and good luck on your journey!
Thanks for the tips! I do actually have a scanner, but when I use it to scan my drawings, it misses the fine blurry smudges I do with the tip of my finger (for shadowing etc.), and that messes the drawing up a little. I haven't really tested it well enough, so I'll take your advice. Thank you!
