The first thing that stands out at me is the odd-numbered Con and Int scores. You'll want to boost both of them to 14 fairly early on. I'd also strongly recommend the War Caster feat, so you can perform somatic components of spells while you're carrying a sword & shield. Your Int score will likely never reach the heights of a full caster's spellcasting stat, so it may be good to focus on spells that don't require a spell attack roll or an enemy saving throw. Something like the Shield spell early on will definitely come in handy, and if that's the only think you use your 1st-level spell slots for that's not a terrible thing. Protection From Evil & Good can be handy IF you find yourself running into those monster types. Obviously if you're in an undead- or fiend-heavy campaign, it becomes more useful. Pay close attention to the levels where you can take a spell from any school. The 2nd-level list has some great buffs like Blur, Mirror Image and Invisibility. For cantrips, if I was building an EK I'd look strongly at the Booming Blade & Green-Flame Blade cantrips from the Sword Coast book. They don't require a spell attack roll, you make a regular weapon attack. It does mean you'd only make that one attack on your turn, so keep that in mind when you're at higher levels and have multiple attacks. But GF Blade can hit two creatures at once, the 2nd without any sort of roll. If there's two enemies standing next to each other, swing at the one with the lower AC, and the higher-AC guy just takes the damage automatically. With Booming Blade, you can lock an enemy in place unless he wants to take a double-dose of Thunder damage. Good way to keep someone focused on you and off the squishier members of your party. And the damage from both of those cantrips scales as you level up, so they could be situationally better than simply attacking multiple times.
Did you choose Human or Human(variant) for your race? If it was the variant, what feat did you start with? What does your Fighter use as his primary weapon?
