I've been planning to do this for some time now: My very personal improvement challenge.

My art doesn't really get better because I only draw what I'm remotely good at and don't practise -> I can only draw portraits, not whole characters, nor scenes, nor landscapes and so forth -> I want to improve so badly though -> I need to get back to the basics and practise, practise, practise and practise some more!
Meaning: You'll not see any digital art from me for the next three months (at least). I'll be doing anatomy exercises, perspective exercises, landscape drawing exercises etc. etc. in that time - all traditionally, with good ol' pencil & friends. I'll be practising every day (like I should have been for the past few years) and will upload any and all of the results to this newly created gallery folder here:
[link] No worries, I won't spam you with this stuff every day, only twice a week
I'm not only doing this for myself though. I hope I'll be able to share the experiences I make, to help other people who want to improve. I'll probably write a tutorial or two in the end as well

Maybe someone gets inspired to improve their own art through this too, which would be really great. Actually, I have a pretty detailed outline on what exactly I'm going to practise, including a long "Why am I doing this??" section, but I felt it'd be too... I don't know, kind of overbearing or presumptuous to post it. You're more than welcome to follow my struggle for improvement though^^
And if you think 3 months is not enough, well, you're right. I will keep practising after that time span is over of course, as there's always something to improve. No artwork is perfect, no matter if you can see mistakes or not. (You should worry if you don't see mistakes... but that's another story altogether.) But, I'm not a start-from-zero-beginner either. I have been drawing for years already, I've just not improved the way I could have, since I didn't practise enough. Yay for change!

Lastly: The "official" time period of my improvement challenge: June 15
th to September 15
th How is this a challenge?? I challenge myself to improve my art drastically in the period of 3 months
