I think that if you really feel like devoting your time to web designing then web designing is what you want. If it doesn’t work out, there’s always another day with new opportunities. I just looked at your website, it is SO cool! I think that you are very talented at it and that trying it out won’t do any harm. Just make sure that becoming a web designer is work (if I know anything), and you really have to want it to succeed. But i’m sure you’ll do great, good luck!
