Your penis looks quite normal. To help with the rough skin keep all forms of soap and other body cleansers such as shower gel away from your penis. Wash it with water only, then always make sure it has been fully dried.
Get yourself some liquid Coconut Oil used for skin rather than hair - 99% pure is really good. Apply a light coat after taking a shower and you have completely dried yourself. Can also be used as a lube for masturbation - but not safe with the majority of condoms.
Your penis looks completely normal for a circumcised penis to me. Obviously the glans has changed from a pink internal organ to an dry external organ since your operation so over time it will naturally dry out and keratinise (harden over). The skin of the glans is very thin compared to usual skin so hardening takes place on the outer skin to protect it from rubbing and soreness.
