I biggest thing that stands out to me is how the image is not very crisp and clear. I would get a new picture of the jump (because that is your main selling point).
I agree with mizaks. Trying to make a quick buck isn't a how people become successful on the Internet.
I have a domain that i run this website through directly. http://the-vertical-jump-bible.com But i was trying to make a blog about this also. I guess the blog needs some work. It has to be about Vertical Jumping though.
get a unique look to the site, the image could be abit more crisp it looks abit out of focus. other than that nice concept and i think you could sell it.
It's simple and strait forward. Good pick on the template, one of my favs for Blogger. Please try to improve on the image quality though. Thats one of the biggest mistakes lots of designers make, details are details.
Well its just one simple post which will maybe get 100 views a year - if you really want to make something that will make you some money make a real blog about basketball and advertise this on it - also not just having a picture a video would do so much better...
