Hey everybody! Here you have another project I´ve been doing these last days, a Deathknell Watch, from Games Workshop. Any advice or help would be really nice for me. Thank you.
Hope you like it:

The stone looks great and moss and dirtiness make it interesting to look at, which a lot of stone terrain isn't. The only criticism is that the wood looks flat and heavy - it is also much more saturated (amount of pigment) than the rest of the piece which means your eyes are drawn to it. You might want to consider a couple coats of wash, and some desaturated highlights, on the wood.

I was just thinking the same thing before I read your post. The stone work on both looks amazing!

I forgot to write it´s a WIP on the subject of this post! Yeah you are right, the wood needs more work. I know, it only has the base color. It will have highlights and washes. When I finish it I´ll upload a photo.
Thank you for your comments!

I'd try using a duller effect on the wood. The tower looks amazing, mossy and a little run down, but such a bright colour of wood might look out of place.

Have you considered the following:
Eshin Grey as a base
Agrax Earthshade Wash
Greenshade Wash
Steel Legion Drab drybrush.

Gives a more aged and slightly moudly oak effect.
