I agree with DW and Star about hair and lighting. Did you make your own Spidey suit texture? Spidey's one of the harder ones with all that webbing (something I know first hand!). The webbing on the feet is not quite as finished as the rest. Did you make your own Juggy suit too? It looks cool and I don't recognize it. It's a cool series and I'm enjoying really enjoying it however... I'm kind of quoting Scott McCloud here as I discuss what makes comics work when he talks about a magic that happens in comics as your brain fills in the gaps between images to sort of create a movie in your head. Here's an example by DW:
Evil Rising: Conclusion Page 2 Notice how he makes the action flow from one panel to the next. There's a bit of a disconnect between your images in the series that feels more like a slide show. In the first and second, Spidey and Juggy are in almost the same position. One really need to read the text to know what happened. You should consider have Spidey getting clobbered in the second image and Hulk stepping into the 3rd pic, which would give a better feel for the series and bring it to life so we're making that mental movie connection more. Does that make sense? Anyway, enjoying this still and looking forward to seeing more!
