Change of blogskin

Eh guys as you can see our blogskin isn't really anything terrific. In fact, it looks quite noob compared to some CO blogs. Right now its just a picture with a light background that scrolls down together with the black text. I've been trying so hard (and no success) for the past two nights to change the stupid blogskin but the stupid message keeps appearing that says my coding is incomplete when I'm pretty sure I pasted the whole thing into the html column. So... if anyone knows how to make this blog look nicer... please help... can try with the rico tanbo 2 blog first.
