The wood is rather large, but you can "hide" some of it with plants. You can plant around it, behind it, over it and on it. Anubias, mosses, and even plants like glossostigma elatinoides will grow laying/tied to DW.
You need more plants. Take a gander at the ForSale forum and see if there may be some there you like. People sell plant packages that are very reasonable.
Isn't this fun?! We get to play in the water and are actually encouraged to do it!
