I think you need more contrast. Too many of the fabrics are in black and brown and grey tones that merge together, and at least a couple of the textures are very similar. Try starting over with a different focus fabric that has several colors in it, then choose fabrics that pick up those colors. Also it helps a lot to have a small amount of a "deep dark" fabric and "light bright" fabric in the block.
The bright yellow of the cutting mat peeking through actually livens up the block. Try changing out the golds and browns with brighter versions of yellow.
