I’m attempting to work out some stuff and as a means to unwind, I’ve decided to revisit my Next Gen setting, so here’s some quick ‘n dirty sketches of some boys.  
 
Seen here are the sons of Princess Twilight Sparkle and Prince Consort Big Mackintosh, of the historical Apple Clan. Twi and Mac are stupidly fluffy and love their boys more than anything, but all the love in the world can’t shelter kids from all the issues…  
 
Seen here are the boys Discovery Apple (above) and Ambrose Apple (below). Despite his shorter stature, Discovery is the first born and Twilight’s heir, even through he was born a pegasus. He clearly takes after his mother, and by that I mean her habit for isolating for hours on end with a stack of books and being a total nerd. He’s not as bad as her, where Twilight once thought that friendship was pointless until she literally saved the world with it: Discovery does have friends, he just knows what the limits with his patience are and needs to unwind after interacting with others, usually in the library. He’s also a bit of a snob, thanks to spending more time with the higher society types as he pursues his education, but that farm livin’ comes out now and again when he’s riled up. His talent lies in being amazing with machinery and him wanting to use that talent and his position as a prince to build up Equestria into a more technologically prominent nation, so the ponies are less vulnerable should they be without magic thanks to some villain.
