I always do thumbnail sketches on the backboards of my drawing pads, and as I just used up a pad I scanned the backboard before throwing it in the recycling bin.
Top left are two sketches for Fields of Stone, the top one being most like the result, though I decided to not go with the pointing arm.
Bottom left is the thumbnail for The Hunt II. Top middle (and very faint one top right) is a spidery idea I haven’t made into something yet.
In the middle are two sketches for Crystal Guard. To the right is a thumb for She Wolf, and some armour sketches for the same.
