I like the colors, diagonal comp, and the sharpness of the face and claws. Would've liked to see him more towards the URC (as viewed) with some more space to crawl down and in to.
Hi Milan,
Very good advice offered above.....may try lightening the body of the crab body...just a touch...to make it stand out from the BG a bit more also.....or you could go with darkening the BG a bit for the same effect.
Very nice image Milan. I also recommend lightening the crab just a touch to give a more 3-D feel to the image and to highlight the great detail you've got there.
