Also, If I waited and practiced till my skills matched up to how I want my current webcomic to look. It'd still wouldn't be made. I just took the leap and thought it's better to have a poopy comic than no comic at all.
Making a comic is actually a good way to get better at drawing. Sometimes you get better midway through a single chapter, which leads to another problem people have is "Do I go back and re-draw old pages now that I'm better?" (Which I'd say no) Again it's better to have a "poopy" comic than no comic at all.
(keeping my lingo PG)
It the end it's up to you. If you stick with hiring an artist, It depends how long the project is. Is it a long running series? a short story? somewhere in between? and if it's in between you need to be upfront with the artist with how much you're expecting.
Also how much creative decisions does that artist have? is it more 50-50? 0%? some Artist are fine with either way. As long as you're nice and upfront about it then they know what they're getting into.
Best of luck!! Keep going!
