Basically the photos show that your penis has developed in a normal manner. However, as the photos are not particularly clear on detail, you may have slightly unhealthy skin due to exposure to any form of body wash, such as soap, shower gel and so on. Limit the exposure to your penile skin as much as possible and try to use water only to wash your penis with when you shower or wash your penis after you have urinated.
Before getting in the shower draw your foreskin forward away from your body so that the head of your penis is fully covered. Wash the rest of your body AND fully rinse. Expose the head of your penis and simply use the warm - never hot - running shower water and the inside of your hand and fingertips to clean the head and inner-foreskin of your penis with. When you get out of the shower, or simply wash your penis, always make sure the skin on the head and inner-foreskin is fully dried. You should only be using a towel that ONLY you use.
In terms of your urine this is very much dependant upon the amount of fluids that you drink on a daily basis, and whether you drink a great deal of things such as caffeinated coffee everyday. Essentially you need to try drinking plenty of water everyday for 2 to 3 weeks and see whether this regulates your urine.
The ideal fluid intake is around 2 litres per day and a substantial part of this should be water
