You're clearly a very talented artist. The drawing and colors are very appealing, and I like the way you manage to close each strip with a gag/climax even though it is a continuing story.
Suggestions for improvement:
You might want to vary the line weights for the main characters, depending on distance, etc. The constant line weights rob the drawings of depth and make them a bit flat.
You way want to install a nicer commenting system like Disqus.
I like the clean, simple layout and easy navigation. However, that bright purple is a little strong. Maybe a a quieter background color?
