I'm still very early on in comic creation, so I haven't hit too many, but there are some I have accomplished so far, and a few I'm striving for in the near future (hopefully haha)!
So I got the initial idea to write a one-shot comic in February. I quickly figured out the relative length and plot, but the first milestone I hit was to actually get the whole thing written down in a word document, which allowed me to edit it down more easily to fit the scope of the project (I knew I wanted a ±50 page project). So that felt good!
Next was drawing a complete story board version of my story! I ended up overshooting my page count a little bit (ended up at 66 pages) but it felt so good to have a completed story drawn out and in my hands (virtually, anyways)!
My most recent minor milestone was simply starting the finished pages. Taking that first step is hard o-o I now have 5 completed pages :]
The next milestone I'm aiming for is actually a major one from my perspective. I'm very much looking forward to the point where I have enough buffer to actually start uploading! I'm hoping to reach that point by next month, maybe
We'll see, a lot of hard work ahead before that point though xD
