Hmm, if I had to pick one, I'd probably say I'm really proud of how far my backgrounds have come, especially just over the last year and a half since I started my comic. Backgrounds are never something that I particularly disliked drawing... but I was also always just so bad at them hahaha. I think the biggest thing that I've practiced and that has contributed to make them better is spending more time studying what I'm drawing to draw and how to detail/render it properly. What was always the most "off" about my backgrounds before is that I would just draw from imagination without doing much or any research, and so everything would look really simple, undetailed, and just generally unappealing.
It's amazing how far a little texture and detail goes. For example, I have these two panels that show the same scene, one from the beginning of the comic (page 11) and the other from the end (page 64.) The first one's not too bad, I defintiely pushed myself to spend a little more time developing the buildings for this first city scene that I had done in previous projects of mine:
Buuuut I kept pushing to improve them more and more as I went along, and by the end of the comic I was adding some texture to the street and decoration (the green strips that go along the side, those got added around page 15 I think lol) and it looks much better already:
I also like to show off this first panel of a side project I did last summer... my main goal for this comic was just to go all out on the backgrounds and hope that I improved a decent amount in doing so, so these were a lot of fun to draw xD
