Quarter horse x warmblood 4 year old gelding

Blue is our 15.3 gelding. Beautiful blue roan , (not grey)We have had him from a foal , backed last autumn and he’s taking everything in his stride. Hacking well around the moors and roads now , goes to the beach regularly, nothing much bothers him , he’s good with open spaces , rivers , cars ,he can be ridden in a bit less bridle no problem, and has just started neck raining , and responding well, still green and not for a total beginner due to his age , he’s presently shod, but happy to go barefoot,
