Looking at both shots you uploaded ... I'm sure fully there is any nose art there. The plane marking is the Black triangle then the digit 10 , the cross and then the 03 or 23. None of the Hs 123 I have seen in pictures so far, had any nose art painted at the cockpit area. As I have mentioned the Gruppe/Staffel emblem was applied between the back of the engine cowling and the front of the cockpit. Your picture doesn't present the part of the fuselage. The RLM rules for pre-war markings of the Luftwaffe planes were quite strictly followed. In your second shot uploaded even the Swastika applied correctly on the tail can be noticed as well.
