I got two. My first project 'WYIHN!', and my current one 'VTGtaHR'.
'WYIHN!' was/is more of a prototype comic, which is now over 100 pages in. I created it to get my foot in the door, and start learning the basics of how to comic. Since it was mainly just to get myself started, the story is rather weak, there's a lot of little holes and it sort of drags on with not a whole lot happening. The type of comic I made it also put some restrictions on what I could do with it, so it hasn't been particularly fun to work on, and the main character is also an unlikable brat.
'VTGtaHR', while also being a practice comic (to improve my backgrounds, and story "skillz"), it is definitely my favorite. I had fun with some of the characters from my other project, so I decided to work on a story revolving around them, with a mature theme so I had more the work with. The comic is all around enjoyable, and I have to admit was a refreshing change from the other project, which I have been trudging through for a good 6 or so years. It is far from being great but I put a lot more effort into the construction of the story for this one, and while I did my best with both, it does take longer to finish pages for 'VTGtaHR' since they're in colour.
In short, 'VTGtaHR' is my favourite.
