I'm not new but I'm happy to announce that I'm progressing.
I don't want to attribute my confidence in becoming better from acquiring my first tablet (trust me, it was hard to learn at first), but it certainly made things easier after I got used to using the durned thing. (It's a GREAT investment, for a hobbyist like me and more so for Art students and real professionals in digital art, haha). After much practice doodles and not saving them, I became accustomed to drawing without looking at the surface where I'm drawing, haha.
Before the tablet, I think I proved to myself that I could color in things with just my mouse I had to tediously use the pen tool often though, haha (but I liked being OC about making the curve so bonus for me).
Made before the tablet: (digitally colored) (drawn and digitally colored) ---> I used MS Paint of 2007 for this one And then I lost patience haha ---> Well, I re-drew the line art using GIMP and then colored it in with Photoshop
Made with the tablet: (digitally colored) (drawn and digitally colored)
I know it's mostly fan art but I've resolved with myself that it's okay because I can practice using characters I enjoy drawing What I do now is try and get the line art as luverly as possible before I scan it. That way, I also practice inking and shizz. Hmm. It's still a pain to clean up the line art digitally but it's like a huge sigh of relief when you're done, haha. Slaving away has its merits In this case, you get neat and clean line art. Actually, haha, I'm trying to learn how to use watercolor as well. It's deceptively easy and yet not
It's great that you want to chronicle your progress That's the best way to move forward. Even I keep my drawings from about 6 years ago. It's fun to look back at them and see how much I changed. Good luck!
