Track 1 - I think less reverb and more balancing is in order. Everything sort of gets muddled together, especially when there's this higher melody coming through at around a minute in that I really want to be able to hear better - it sit above everything else. Otherwise I think the piece did a good job of evoking the theme you were going for!
Track 2 - Again, could be balanced some more and the overall volume could be reduced. I especially liked the solo part around 0:35 but everything after that again melded together.
Overall I'm not well versed in electronic music but it felt like it could be a great video game backdrop with some more mastering!
