How does my weight lifting routine?

Everyone being different all I can do is give pointers. Your workout looks good. I went for being ripped and cut and found that keeping the weight lower than I can max worked better for me. I'm 6ft around 175 and less than 5% body fat. For cardio I went more for individual sports like cycling, handball, tennis... Seemed to get better results. Leaner muscle mass proved to be good as I got older, lower weights and more reps is easier to maintain after injuries. Looks like you got a good plan. Go with more dumbells and you'll see a more symetrical build.
