This looks pretty solid to me. For prettier arms though I think there's no harm in adding 2-3 sets of skullcrushers or pushdows instead of dips to assist slightly in growth if the dips turn out to be too much. I myself have used a full body routine very similar to this and made excellent progress in terms of body composition and strength, however developed a lower back issue as well as overall soreness and fatigue as the weights got heavier and switched to training each muscle twice a week instead of three as it suits my lifestyle and needs better. Just something to think about down the road.
