In the last little while I have stumbled across some great comics and thought I'd pass on some great sites for you to check out.
The first I will tell you about is Butternutsquash which I found late last week. It is an amazing strip and the artwork is some of the best I have seen on the net. It updates every Wednesday and I would really suggest checking that out.
Another page that I found recently is Bug and Slug which just started recently and seems to be on the right track. It's about a couple of aliens that crashed into earth and it quite well done.
Another comic that I would like to bring to your attention (which isn't so new) is Tastes Like Gravel. I actually did a guest strip for them which they will be posting this Wednesday but I would really suggest checking out the page before then.
