Uncanny Orchestra - Not really feeling the drum sounds in the intro, later brought back at 1:43. The snare doesn't fit the texture of the orchestration, plus the drums are somehow just as or more prominent than the brass harmonies. I'd examine some more orchestral mixes and see how the percussion work compares to yours, both in tone and volume.
Beyond that, obviously the composition itself is only in the intro stages, so more writing ideas will show up, and the drums would hopefully end up being more varied, since this was a quick WIP as you said.
Some random ideas. Think of a way to incorporate or interpret the Spider-Man bassline from :03 and :24 of the SPC
Don't be afraid to grab other ideas from the Spider-Man & X-Men soundtrack now that you're outside of PRC100 and this WIP isn't locked into anything. Stuff like :15 of the Title theme, :08 of Briefing, :26-:42 of Cyclops, the string synth from :08-:31 of Gambit, could be pretty interesting given an orchestral take.
You could also explore other Follin soundtracks and go outside the box. Why not give Wolverine by Geoff Follin a look as well (e.g. Track 23).
Ride the Sky - Obviously, this sounds closer to completion. Bassline at 1:06 should be bumped up. It's not audible and plays 0 factor after 1:11 once more instruments come in. Better at 1:45 though.
I thought the dynamic change at 1:45 wasn't as effective in the execution as the writing intended. Can't put my finger on it, but I'll hit some Js for feedback; there's something about the texture of the brass with the drums that doesn't quite feel right.
The brass sample still lacks in realism, though the sequencing is ok AFAIK. Perhaps listen to DZComposer's material to hear what he may be doing differently than you. It's not bad though. Better changeups at 2:21 and 3:10. Lemme see what more I can dig out of some colleagues to help you refine this.
