I'm watching Seva's stream and at 37 in, these are my thoughts sans those already said by Omni.
On a note for graphics, don't extend some and then redraw others, you'll lose out on inconsistency. It's already an issue in the first few cutscenes.
I definitely agree with Omni on the initial comments he made during the first cutscene about story stuff. Harken mug looks iffy.
And that's my opinion's based on the first 17 minutes.
I've watched 20 more minutes, why is there so much name dropping of FE7 characters? It's stupid on two fronts, it makes your world seem smaller 'cause instead of filling it in with more characters you just keep going back to the same pre-established characters and secondly, it exists solely for "Hey look you remember this character huh how cool is it to see their name callback callback callback fanservice for no reason look at us".
Now I'm 2 hours in...
Finally met the daughter character, and why?
Like, not only is it an old mug by Aeo, Omni says it was a character in a different hack? Like, that's jarring.
But holy shit do her and the mask guy look so out of place. Like, I'm sure Aeo would say the same about my works and I don't mind, but her stuff does not mesh at all with regular FE mugs, they're overdone to the point of ridiculous.
Lance's hair changes look bad, not better than the original, the red knight's changes are unnecessary and again just cause jarring, Wolt's hair is literally terrible and Miledy is an abortion if you were trying to go for the original design.
Also, I know they were both from Elibean Nights, but the Zephiel and Eliwood mugs are both dodge as fuck.
Along with Gwen and Lilina but I think I've ragged on this enough...
