I think the banner/title one is great - and it does look better than the last one (that was great too, but I like the DNA strands in this one better, plus the background formulas).

The wallpaper one looks great too - really like it! You're so talented!

Now, get back to that writing...!! *grin* And where is the sequel to Thicker Than Water, hmm?!!

EDIT: Love the icon too!!!
