The Wolfpack has always been my favorite castle theme, (along with the forest guys). Shame they only released 4 or so sets.
The wolfpack tower had great promise, but it never actually looked like a tower, more like a shed on a hill, so i bought two slightly incompete sets on ebay for about $20 each. (One of them had some extra pieces and extra minifigs too!). I also added a few old gray bricks i got for free in a pick-a-brick deal with the lego imagination center.
I ended up with this thing. I didnt measure it but it was probably about three feet tall including flagpoles & such. Its dismantled now, and the pieces are used in a railroad bridge. (isnt it typical? a great mideval castle scavenged for its building materials just like many real mideval constructions).
the pictures are a little dark, my apologies for that.
