With the current coloring scheme it is very hard to distinguish occupied squares from empty squares; the pieces blend in too easily with the bright square and arrow colors. I would recomment to decrease the saturation of all the board colors by at least 50%. E.g. by giving the image a 50% (or even 70%) transparency and have a whitish background shine through.
