It looks a bit cut and pasted because the robin has had his toes cut off!
Photos as logos always look a bit awkward compared to a drawing/illustration - and it's easier to print them badly. The robin has certain seasonal connotations, it might be your name but the image is perceived and assessed by the brain a long time before the text is read.
It's a personal thing, but I'd suggest "Robin Chun, photographer" sounds and reads better than the concatenation "Robinchun Photography".
