Your art style is really nice. Almost like a painting in some panels, though I think it would benefit from being a little sharper with less blurring
. My biggest gripe is that the font is very stark and plain (this might be what you're after, if so, stick to it!). It might attract the reader to have a more interesting font. There are plenty of traditional word balloon fonts that you can use for free on the internet. Blambot is a good resource for those.
I've only recently joined Tapas. I uploaded my first issue of my comic the other day. You can find it here:
Keep up the good work!
