I saw you post your second comic page to tumblr just a few minutes ago and wanted to point out that you should definitely make use tumblr's tag feature! It'll get you some much needed attention! I saw you used it in the first page, post but, you made all your tags into one giant hashtag...
So yeah totally seperate your tags like
#worldofvim #vim #magic #webcomic within tumblrs tag function.
Lastly the biggest thing to remember(i think all search engines work like this) but only the first 4 tags actually pop up in search engines and in tumblrs search bar. So try and make your first 4 important to your posts like
#worldofvim and
#webcomic for sure. Otherwise every tag after that is mostly just fluff that can be used to search within your page, but won't make your posts pop up anywhere else!
Also, if your going for an even more webcomic feel, there's a specific tumblr theme made for webcomics! It has that nice first, previous, next, last option for "reading" and you can put about pages and other jazz like that into there!
