I like a lot of these Feats and how there's batches of them playing with different themes and angles. If nothing else I think they're heading in the right direction for the majority of these race feats.
Using Feats to expand on already existing race features; with Bountiful Luck, Critter Friend, Wonder Maker, and Drow High Magic feels like a good space to toy with and gives players a chance to lean into their specific race.
Using Feats to touch on class and sub-class features but in a way that's thematic to the race; with Orcish Aggression/Cunning Action: Dash, Second Chance/Cutting Words, and Fey Teleportation/Mysty Escape, Everybody's Friend/Beguiling Influence, is a fun idea to be able to double down on a class feature. For example a lvl 6 High Elf Feylock with the Feat will be poofing all over the place, none stop, with 2 short rest teleports. That sounds like fun. But if a Half-Orc with Orcish Aggression goes Rogue and gets Cunning Action then hes basically stepping on his own toes. Normally I don't mind overlap with general Feats and features but I think that specifically Race Feats need to be mindful of the difference between overlapping and doubling down. So maybe make Orcish Aggression give you 90 ft to move towards an enemy, essentially a Bonus Action Double Dash. And now the Half-Orc has the option to run 90ft towards an enemy or 60ft away from an enemy for a Bonus Action.
I also like the idea of taking general Feats and tweaking them to be race specific; Lucky/Human Determination, Skilled/Prodigy, Magic Initiate/Wood Elf Magic. But it brings up interesting balance questions. "Is two cantrips, and a 1st level spell from any class more/equal/less then a cantrip, a specific 1st level spell, and a specific second level spell?" "Is three Luck Points per long rest more/equal/less then one free advantage every short rest?" "Is three tools/skills worth more/equal/less then a +1, a skill, a tool, and a language?"
Also it brings up the question "Should Racial Feats be stronger then General Feats since they have a prerequisite?" Which I don't think we've even started to discuss yet.
Concerning Barbed Hide and Dragon Wings. I don't have an issue with the sudden change, who among us hasn't looked in the mirror and thought "When the hell did THAT get there?!" Freakishly long single back hair, or Giant bat wings, its all the same really. Plus the reveal can be fun. 'Tiefling sits, starts eating breakfast...sneezes...SPIKES..."AAAAAAHHHHHHHHH!!!!"'
I also don't mind Dwarf Resilience even if they can heal HD without a rest. It's already balanced with the HD and the fact that he'll have a party to force him to short rest. Actually sounds really thematic for a Dwarf "What do you mean you want to take another rest?!? We just had one 6hrs ago!... That axe barely nicked your head, that bastard monster ATE me and you don't hear ME complaining...I expect this nonsense from the Elf, but from you? You're a Bloody Dragonborn...Fine,fine babies let's take a rest, want me to kiss your wittle ouchies too?"
Also, now i want to play a Half-Elf Thief with Everybody's Friend, Skilled, and Prodigy. That's like 12 Skills, 6 Expertise, 3 languages, a couple tools, and Reliable Talent, would make a fun little Skill Monkey.
