Oh cool! I'm in the middle of illustrating a steampunk comic that will be intended for print, so I'm always looking for inspiration and new steampunk comics.
Things I like:
-The artwork (lineart) is really good, especially for a webcomic. I'm not a big fan of digital coloring, but the coloring is also well done.
-I'm a huge Tesla fan, so it's nice to see that he was incorporated (you also incorporated Houdini, which is cool, but I'd say be careful not to accidentally retell something that already happened in The Prestige).
-The lettering is well thought out and properly placed. I like that the word balloons are in color. The one thing that is a TAD distracting is, because the balloons don't have a border/stroke around them, you can't always clearly see the tail. I'm mainly looking at the last panel of page 4. You can barely see the tail, BUT it is still clear enough as to who is talking. Right now, I don't think it's a huge issue, but it's something you and your letterer may want to keep in mind.
-The writing seems good, but I'll have to read more as it progresses to make a definitive opinion. Looks to be going in a good direction though.
So far so good! The one thing that I noticed, however, is that so far there aren't really any steampunk elements to it, beside the compound-bow. So far it just seems to be a turn of the century comic, which is also very cool, don't get me wrong. But right now it isn't really steampunk.
Final thoughts: looking forward to reading more!
