Easy fixes that will improve the game a lot!
#1, most important, so easy, so neesecary: GET RID OF VEE!!! Have another character be the narrator, even Coach Frank again! Vee is annoying and not cool or funny in any way, it's almost like her lameness is a parody of herself, except it's actual torture for players.
When placing objects, let duplicate / similar objects snap to each other to align properly. I hate spending a bunch of time trying to get quarterpipes to be lined up without having uneven ground between them. Same goes for the end / edges of rails and boxes.
Show better highlights after challenges. It seems like it always tries to get what it thinks is the "ender" but it usually just shows me messing around at the end of the challenge. Whatever trick I did that was worth the most score, just show that, and make sure the highlight starts early enough to see the trick setup, not just the make and roll away.
Add more music... I see that you guys are already starting to do this but I think your goal should be to have the biggest game soundtrack of any game in history. People used to talk about the Tony Hawk Pro Skater soundtracks as stuff of legends. EA Skate could be the new king of that throne.
Continue to do more brand drops and try to get many more actual skateboarding brands involved in the game.
