I've worked hard on creating these themes and claiming any or all of my codes as yours is just plain rude
This is pretty much akin to stealing and I've placed the credit link in a way that fits in with the theme and I'd really like it if you'd leave it where I put it. Even if you change parts of the css/html, keep the credit where it is.
don't use as a base
my themes are made to be used right away, not for people to steal and convert to their themes. Use my themes to learn and edit as much as you want, but don't claim it as your own. At the end of the day, it's so much better when you can do it yourself.
NOTE: please do let me know if something isn't working with my themes and I''ll do my best to help you
